Dedication To our readers, well wishers, authors, translators, team members, people who have written about Gonit Sora in newspapers or magazines, collaborators, sponsors and those who inspire us every single day. Preface To whet our hunger for knowledge in our childhood as well as later, we realized that some information is not readily available. To make such kind of information available to our younger generation as well as others, we made a small effort in that direction by launching the online bilingual (English and Assamese) magazine, Gonit Sora on 21st April, 2011. To prepare articles related to some mathematical theory explaining it’s depth and beauty; to write about new research directions and present it in a way accessible to youngsters; to encourage students as well as others to appreciate the hard work of many mathematicians in creating the mathematics that is ubiquitous in the achievements of science and technology by publishing their interviews and biographies; to provide solutions and exercises for students participating in Mathematical Olympiads and other examinations; to provide career guidance for students in need, etc are the main aims of the website. In fields such as acting, sports, music, politics, etc there have been many different groups and people who actively bring forth the stellar performances in those fields. But in science and mathematics, only a small pool of individuals are aware of the latest developments and stay updated with these fields. It is our duty to give impetus to improving this gap in information distribution. With this wish in our mind, a team of two has transformed into a family of over dozen team members, excellent writers, collaborators and our esteemed readers. Amongst our many collaborators, World Scientific’s Asia Pacific Mathematics Newsletter, Mathematics of Planet Earth and Shutterstock.com are the primary ones providing us support in different ways. In the compilation of this e-book, we have used numerous illustrations from shutterstock.com. Till date, we have published over 550 articles in various categories on the website, and from those we have selected just 70 articles to include in this e-book. It is hoped that new readers will get an overview of our articles from this effort. We also hope that every reader will find something of interest in this e-book. At the end, we would like to humbly request our readers to send us any article about mathematics and/or science and technology that they may wish to publish in Gonit Sora. ব ৌদ্ধিক তৃ ষ্ণা পূৰণৰ অৰ্থে ককৰ্ াৰ তথা পৰৱতী সময়ত হু দ্ধ চাদ্ধৰও দ্ধিদ্ধিদ্ধি সমল আদ্ধম দ্ধিৰ্ে ওচৰৰ্ত বপাৱা িাদ্ধিৰ্লাোঁ বসইদ্ধিদ্ধি বতৰ্িদৰ্ৰ দ্ধ চাদ্ধৰ থকা আমাৰ অিুে তথা আি সকৰ্লাৰ্ৱ পা ৰ াৰ্ আমাৰ দ্ধিেৰ সামথেযৰ্ৰ সামািয ৰঙদ্ধণ আগ ৰ্ াৱাৰ উৰ্েৰ্ য গদ্ধণত চ’ৰা িামৰ দ্ধিভাষীক (ইংৰাজী আৰু অসমীয়া) অিলাইি আৰ্লাচিীিি ২০১১ চিৰ ২১ এদ্ধিলত মুকদ্ধল কৰা হয়। গদ্ধণতৰ ক ান া এন াটা বিষয়িস্তুৰ অন্তব িবিত তাবি ধাৰণা আৰু তাৰ কসৌন্দৰ্যিয সম্প ীয়কেখা প্ৰস্তুত ৰা; বিনেষণাত্ম া গনেষণাৰ তু বিশ সম্প ীয় তথ্য তথ্া সৰল িযাখযাত্ম কেখা প্ৰ াশ ৰা; বিজ্ঞা- প্ৰৰ্যুবতিৰৰ বি ানশ সমাজলে অ া সুখ-স্বাচ্ছন্দয গবণতৰ বৰ্য তু আবেষ্কাৰৰ িানিই সম্ভে হিনে কসইসমূি অধযয় ৰ িানি অনিা-পুৰুষাথ্ি ৰা িযবতিৰস েৰ সাক্ষাৎ াৰ িা জীে ীমূে কেখা প্ৰ াশৰ জবৰয়নত োত্ৰ-োত্ৰী তথ্া সিিসাধাৰণজ ৰ উনেনশয গবণত-বশক্ষাৰ 巁ৰুত্বৰ প্ৰসাৰ ঘনটাো; আদ্ধলদ্ধিয়াড আদ্ধদৰ সমসযাৰ অিু ীলিমূলক সমাধাি আগ ৰ্ াৱা; োত্ৰ-োত্ৰী ক বৰয়াৰ সংক্ৰান্তীয় পৰামশি প্ৰিা ৰা ইতযাবিনয়ই আনোচ ীখ ৰ প্ৰধা উনেশয। অবি য়, ক্ৰীডা, সংগীত, ৰাজ ীবত আবি সিনজই বচত্ত আনোড াৰী বিষয়সমূিৰপ্ৰচাৰ িা চচিাৰ িানি িহু সবক্ৰয় এন া এন াটা িৃিৎ কেণী গঢ় হে উঠাৰ বিপৰীনত বিজ্ঞা -বশক্ষা সংক্ৰান্তীয় প্ৰচাৰৰ ধাৰানটা আমাৰ কিশত কতন ই সীবমত কেণীনয়নি অক্ষু ণ্ণ ৰাখাৰ কচষ্টা বৰ আবিনে। এই ধাৰানটা প্ৰিে ৰাত অবৰিণা কৰ্যানগাোনটা আমাৰ স নোনৰ তিিয। আৰু এই বিশ্বাসনৰ অংশ বিচানপ, আবম িুগৰা ী সিসযনৰ আৰম্ভ ৰা আনোচ ীখ আবজ িহুজ সিসয, কেখ , সহৰ্িাগী আৰু পাঠন নৰ এটা পবৰয়ােত পবৰণত হিনে। আমাৰ দ্ধ দ্ধভ সহৰ্িাগীসকলৰ দ্ধভতৰত World Scientific কয় প্ৰ াশ ৰা ‘Asia Pacific Mathematics Newsletter’, Mathematics of Planet Earth, Shutterstock.com আদ্ধদ িধাি। এই ই- ুকিিৰ অলংকৰণত Shutterstock.comবৰ হুৰ্কইিি িদ্ধ যৱহাৰ কৰা কহৰ্ি। গদ্ধণত চ’ৰাত িতিমা লেন বিবিন্ন বশতা ত মুঠ ৫৫০ৰ অবধ কেখা প্ৰ াশ হিনে, আৰু ইয়ানৰ ক ইটামা বশতা ৰ পৰা মানথ্াোঁ ৭০টা কেখানি এই ই- িু খ ত সবন্নবিষ্ট ৰা হিনে। ইয়াৰ জবৰয়নত তু পাঠন আনোচ ীখ ৰ াম- াজৰ সম্পন ি দ্ধকয়ত ধাৰণা পাি। আশা নৰাোঁ স নো পাঠন ই-িু খ ৰ পৰা ব েু সমে োি বৰি। ব ষত, পাঠকসকলৰ্ৰা সকৰ্লাৰ্ক গদ্ধণত িতু া দ্ধ জ্ঞাি-িিুদ্ধি সিকীয় দ্ধ দ্ধভ বলিা িস্তুত কদ্ধৰ লল আৰু বসইসমূহ িকা ৰ উৰ্েৰ্ য গদ্ধণত চ’ৰাললৰ্কা বিৰণ কদ্ধৰ লল দ্ধ িম্ৰ অিুৰ্ৰাধ েিাৰ্লাোঁ। Nov, 2015 Pankaj Jyoti Mahanta Manjil P.

Coleman 1954–2014 Matthew Baker*, Barry Mazur and Ken Ribet *Correspondence: In Memoriam: Robert Coleman, Professor of Mathematics, UC Berkeley [email protected] Georgia Institute of Technology, Atlanta, GA, USA 1 Biography Robert F. Coleman, an extraordinarily original and creative mathematician who has had a profound influence on modern number theory and arithmetic geometry, died of a sud- den heart attack in El Cerrito, CA, on the morning of March 24, 2014. He is survived by his wife Tessa, his sister Rosalind, and brother Mark, his nephew Jeffrey, and niece Elise, and his service dog Julep. The depth and importance of his mathematical ideas, his congeniality, the joy radiating from his playful disposition, and his sheer inexhaust- ible energy—all this in the face of Multiple Sclerosis, a condition that did not deter him from full engagement with life—made Robert an inspiration to his friends, family, stu- dents, and colleagues. Robert also worked toward making civic structures and laws more appropriate for people with disabilities. His activism is yet another reason that Robert was so widely admired. Robert was born on November 22, 1954 in Glen Cove, NY, USA. He displayed an early talent for mathematics, winning an Intel Science Talent Search Award in 1972 as a high school student. He earned a mathematics degree from Harvard University and subsequently completed Part III of the mathematical tripos at Cambridge, where he did research under the supervision of John Coates.

  • Overview of Some Iwasawa Theory
    Overview of some Iwasawa theory Christian Wuthrich 23rd | 27th of July 2012 Contents 0 Introduction 1 1 Iwasawa theory of the class group 1 2 Iwasawa theory for elliptic curves 8 3 The leading term formula 14 4 Selmer groups for general Galois representations 21 5 Kato's Euler system 22 0 Introduction This is the draft version of the notes to my lectures at Heidelberg in July 2012. The intention is to give an overview of some topics in Iwasawa theory. These lectures will contain a lot of definitions and results, but hardly any proofs and details. Especially I would like to emphasise that the word \proof" should actually be replaced by \sketch of proof" in all cases below. Also I have no claim at making this a complete introduction to the subject, nor is the list of references at the end. For this the reader might find [14] a better source. All computations were done in [46]. Any comments and corrections are very welcome. It is my pleasure to thank Thanasis Bouganis, Sylvia Guibert, Chern-Yang Lee, Birgit Schmoetten-Jonas and Otmar Venjakob. 1 Iwasawa theory of the class group Let F be a number field and let p be an odd prime. Suppose we are given a tower of Galois extensions F = 0F ⊂ 1F ⊂ 2F ⊂ · · · such that the Galois group of nF=F is cyclic n n n of order p for all n > 1. Write C for the p-primary part of the class group of F and write pen for its order. Theorem 1 (Iwasawa 56 [15]).

  • ON GENERALIZED MAIN CONJECTURES and P-ADIC STARK CONJECTURES for ARTIN MOTIVES
    ON GENERALIZED MAIN CONJECTURES AND p-ADIC STARK CONJECTURES FOR ARTIN MOTIVES ALEXANDRE MAKSOUD ABSTRACT. We formulate a cyclotomic main conjecture and an extra zeros conjecture for gen- eral p-stabilized Artin representations, which are shown to imply the p-part of the Tamagawa number conjecture for Artin motives at s 0. We also relate our new conjectures with various Æ Iwasawa main conjectures and p-adic Stark conjectures that appear in the literature. In the case of monomial representations, we prove that our conjectures are essentially equivalent to some newly introduced Iwasawa-theoretic conjectures for Rubin-Stark elements. Along the way, we study the Gross-Kuz’min conjecture from the viewpoint of p-adic transcendence theory and we show that it unconditionally holds for abelian extensions of imaginary quadratic fields. 1. INTRODUCTION Iwasawa theory traditionally focuses on the construction of p-adic L-functions and on their relation with arithmetic invariants of number fields. Concurrently with the first major achievements of the theory [Kat78, DR80, MW84, Wil90, Rub91], several attempts were made in order to define the conjectural p-adic L-function of a motive [CPR89, Coa91, Gre94] and its corresponding Selmer group [Gre89, Gre91]. The motive in question was assumed to admit a critical value in the sense of Deligne and to be ordinary at p, hypotheses which were circumvented in a work of Perrin-Riou [PR95] using the so-called big exponential map and in a work of Benois [Ben14a] allowing the treatment of “trivial zeros” via Nekovár’sˇ theory of Selmer complexes [Nek06]. However, the statement of Perrin-Riou’s conjecture is “maximalist” (in her own words) and is rather not appropriate in certain practical settings.

  • Estimating Class Numbers Over Metabelian Extensions 3
    ESTIMATING CLASS NUMBERS OVER METABELIAN EXTENSIONS ANTONIO LEI Abstract. Let p be an odd prime and K∞,∞/K a p-adic Lie extension whose d−1 Galois group is of the form Zp ⋊ Zp. Under certain assumptions on the ramification of p and the structure of an Iwasawa module associated to K∞,∞, we study the asymptotic behaviours of the size of the p-primary part of the ideal class groups over certain finite subextensions inside K∞,∞/K. This generalizes the classical result of Iwasawa and Cuoco-Monsky in the abelian case and gives a more precise formula than a recent result of Perbet in the non-commutative case when d = 2. 1. Introduction 1.1. Setup and notation. We fix throughout this article an odd prime p and an integer d 2. Let K be a number field that admits a unique prime p lying above p. ≥ Let K∞,∞ be a d-dimensional p-adic Lie extension of K in which only finitely many primes of K ramify and p is totally ramified. Furthermore, we fix a Zp-extension c K /K contained inside K∞,∞ and assume that Gal(K /Kc) is torsion-free and abelian; • ∞,∞ Every prime of K that ramifies in K∞,∞ decomposes into finitely many • primes in Kc. c For example, when d = 2, we may take K = Q(µp), K = Q(µp∞ ) and K∞,∞ ∞ p the Kummer extension Q (µp∞ , √α), where α = 0 is an integer such that p α or p αp−1 1 (such α is said to be amenable for6 p and this ensures that p |is || − totally ramified in K∞,∞, see for example [Lee13, Proposition 2.4(i)] or [Viv04, Theorem 5.2 and Lemma 6.1]).

The classical formulas for [a, j3], state that [, ,3]n= gn1Tn(log9), j3 E l+~n? n >_0, [7n, j3], _ -gn1Tn(~n7r;1log j3), E 1+~n, n ~ 0, [a, ~]o = -go 1To(~oa~i dudao log ~) , a 1+~0 where Tn denotes the trace from to to Qpl). In a previous note [7], we have announced formulas for [a, ~3]n which generalize the above formulas of Artin-Hasse. In the present paper, we shall prove those formulas and then discuss some related results. As in the above, we retain most of the notations introduced in our earlier paper [6].

Dedication To our readers, well wishers, authors, translators, team members, people who have written about Gonit Sora in newspapers or magazines, collaborators, sponsors and those who inspire us every single day. Preface To whet our hunger for knowledge in our childhood as well as later, we realized that some information is not readily available. To make such kind of information available to our younger generation as well as others, we made a small effort in that direction by launching the online bilingual (English and Assamese) magazine, Gonit Sora on 21st April, 2011. To prepare articles related to some mathematical theory explaining it’s depth and beauty; to write about new research directions and present it in a way accessible to youngsters; to encourage students as well as others to appreciate the hard work of many mathematicians in creating the mathematics that is ubiquitous in the achievements of science and technology by publishing their interviews and biographies; to provide solutions and exercises for students participating in Mathematical Olympiads and other examinations; to provide career guidance for students in need, etc are the main aims of the website. In fields such as acting, sports, music, politics, etc there have been many different groups and people who actively bring forth the stellar performances in those fields.

  • Takagi's Class Field Theory
    RIMS Kôkyûroku Bessatsu B25 (2011), 125160 Takagis Class Field Theory ‐ From where? and to where? ‐ By * Katsuya MIYAKE §1. Introduction After the publication of his doctoral thesis [T‐1903] in 1903, Teiji Takagi (1875‐ 1960) had not published any academic papers until1914 when World War I started. In the year he began his own investigation on class field theory. The reason was to stay in the front line of mathematics still after the cessation of scientific exchange between Japan and Europe owing to World War I; see [T‐1942, Appendix I Reminiscences and Perspectives, pp.195196] or the quotation below from the English translation [T‐1973, p.360] by Iyanaga. The last important scientific message he received at the time from Europe should be Fueters paper [Fu‐1914] which contained a remarkable result on Kroneckers Ju‐ gendtraum (Kroneckers dream in his young days): Kroneckers Jugendtraum The roots of an Abelian equation over an imagi‐ nary quadratic field k are contained in an extension field of k generated by the singular moduli of elliptic functions with complex multiplication in k and values of such elliptic functions at division points of their periods. (See Subsections 3.2 and 3.3 in Section 3.) K. Fueter treated Abelian extensions of k of odd degrees. Theorem 1.1 (Fueter). Every abelian extension of an imaginary quadratic num‐ ber field k with an odd degree is contained in an extension of k generated by suitable roots of unity and the singular moduli of elliptic functions with complex multiplication in k.
