Mechanical Aspire
Newsletter Volume 6, Issue 11, November 2016 Mechanical Aspire Achievements in Sports, Projects, Industry, Research and Education All About Nobel Prize- Part 35 The Breakthrough Prize Inspired by Nobel Prize, there have been many other prizes similar to that, both in amount and in purpose. One such prize is the Breakthrough Prize. The Breakthrough Prize is backed by Facebook chief executive Mark Zuckerberg and Google co-founder Sergey Brin, among others. The Breakthrough Prize was founded by Brin and Anne Wojcicki, who runs genetic testing firm 23andMe, Chinese businessman Jack Ma, and Russian entrepreneur Yuri Milner and his wife Julia. The Breakthrough Prizes honor important, primarily recent, achievements in the categories of Fundamental Physics, Life Sciences and Mathematics . The prizes were founded in 2012 by Sergey Brin and Anne Wojcicki, Mark Zuckerberg and Priscilla Chan, Yuri and Julia Milner, and Jack Ma and Cathy Zhang. Committees of previous laureates choose the winners from candidates nominated in a process that’s online and open to the public. Laureates receive $3 million each in prize money. They attend a televised award ceremony designed to celebrate their achievements and inspire the next generation of scientists. As part of the ceremony schedule, they also engage in a program of lectures and discussions. Those that go on to make fresh discoveries remain eligible for future Breakthrough Prizes. The Trophy The Breakthrough Prize trophy was created by Olafur Eliasson. “The whole idea for me started out with, ‘Where do these great ideas come from? What type of intuition started the trajectory that eventually becomes what we celebrate today?’” Like much of Eliasson's work, the sculpture explores the common ground between art and science. -

Introduction Swami Vivekananda envisioned a University at Belur Math, West Bengal, the headquarters of the Ramakrishna Mission. In his conversation with Jamshedji Tata, it was indicated that the spirit of austerity, service and renun- ciation, traditionally associated with monasticism could be united with the quest for Truth and Universality that Science embodies. An inevitable fruit of such a synthesis would be a vigorous pursuit of science as an aspect of Karma Yoga. Truth would be sought by research and the knowledge obtained disseminated through teach- ing, making knowledge universally available. The VivekanandaSchool of Mathematical Sciences at the fledgling Ramakrishna Mission Vivekananda University, headquartered at Belur, has been set up keeping these twin ide- als in mind. We shall first indicate that at the National level, a realization of these objectives would fulfill a deeply felt National need. 1.1. -
Preface Issue 4-2014
Jahresber Dtsch Math-Ver (2014) 116:199–200 DOI 10.1365/s13291-014-0108-4 PREFACE Preface Issue 4-2014 Hans-Christoph Grunau © Deutsche Mathematiker-Vereinigung and Springer-Verlag Berlin Heidelberg 2014 The last few years have been a good time for solving long standing geometrical- topological conjectures. This issue reports on the solution of the Willmore conject-√ ure—the “best” topological torus is a “real” torus with ratio of radii equal to 2— and one of Thurston’s conjectures—every hyperbolic 3-manifold can be fibered over a circle, up to passing to a finite cover. Starting in the 1960s, Thomas Willmore studied the integral of the squared mean curvature of surfaces in R3 as the simplest but most interesting frame invariant elas- tic bending energy. This energy had shown up already in the early 19th century—too early for a rigorous investigation. Willmore asked: What is the shape of a compact surface of fixed genus minimising the Willmore energy in this class? (In the 1990s, existence of minimisers was proved by Leon Simon, with a contribution by Matthias Bauer and Ernst Kuwert.) Willmore already knew that the genus-0-minimiser is a sphere. Assuming that symmetric surfaces require less energy than asymmetric ones (which has not been proved, yet) he studied families√ of geometric tori with the smaller radius 1 fixed and found that the larger radius 2 would yield the minimum in this very special family. He conjectured that this particular torus would be the genus- 1-minimiser. Almost 50 years later Fernando Marques and André Neves found and published a 100-page-proof. -
Generic Transfer from Gsp(4) to GL(4)
Compositio Math. 142 (2006) 541–550 doi:10.1112/S0010437X06001904 Generic transfer from GSp(4) to GL(4) Mahdi Asgari and Freydoon Shahidi Abstract We establish the Langlands functoriality conjecture for the transfer from the generic spec- trum of GSp(4) to GL(4) and give a criterion for the cuspidality of its image. We apply this to prove results toward the generalized Ramanujan conjecture for generic representations of GSp(4). 1. Introduction Let k be a number field and let G denote the group GSp(4, Ak). The (connected component of the) L-group of G is GSp(4, C), which has a natural embedding into GL(4, C). Langlands functoriality predicts that associated to this embedding there should be a transfer of automorphic representations of G to those of GL(4, Ak)(see[Art04]). Langlands’ theory of Eisenstein series reduces the proof of this to unitary cuspidal automorphic representations. We establish functoriality for the generic spectrum of GSp(4, Ak). More precisely (cf. Theorem 2.4), we prove the following. Let π be a unitary cuspidal representation of GSp(4, Ak), which we assume to be globally generic. Then π has a unique transfer to an automorphic representation Π of GL(4, Ak). 2 The transfer is generic (globally and locally) and satisfies ωΠ = ωπ and Π Π⊗ωπ. Here, ωπ and ωΠ denote the central characters of π and Π, respectively. Moreover, we give a cuspidality criterion for Π and prove that, when Π is not cuspidal, it is an isobaric sum of two unitary cuspidal representations of GL(2, Ak)(cf.Proposition2.2). -
Converse Theorem
A strengthening of the GL(2) converse theorem Andrew R. Booker and M. Krishnamurthy dedicated to Ilya Piatetski-Shapiro (1929{2009) Abstract We generalize the method of [Bo03] to prove a version of the converse theorem of Jacquet- Langlands with relaxed conditions on the twists by ramified id`eleclass characters.

Binomial coefficients 38 1. Introduction The \converse theorem" in the theory of automorphic forms has a long history, beginning with the work of Hecke [He36] and a paper of Weil [We67] relating the automorphy relations satisfied by classical holomorphic modular forms f to analytic properties of the twisted L-functions L(s; f × χ) for Dirichlet characters χ. Soon after, the classical theory was recast in the modern setting of automorphic representations by Jacquet and Langlands [JL70], who generalized Weil's result to GL2 representations π over a global field, characterizing them in terms of their twists L(s; π ⊗ !) by id`eleclass characters !. -

Interview with Ian Agol
THE GRADUATE STUDENT SECTION Interview with Ian Agol progressed, I have delved into deeper subjects in math- ematics, including Riemannian geometry and geometric group theory, in order to solve questions in 3-manifold topology. Most of the revolutions in the subject have come from other fields (dynamics, partial differential equations, mathematical physics, algebraic geometry, symplectic geometry, number theory), which is exciting because it requires one to continuously learn new mathematics, giv- ing one new perspectives on the topic. Diaz-Lopez. What theorem are you most proud of and what was the most important idea that led to this breakthrough? Agol. A few years ago, work I did resolved the virtual Haken conjecture. This work relied on expertise of my collaborators Daniel Groves and Jason Manning, as well as on the much deeper work of Dani Wise and his collabora- tors (especially Haglund, Hsu, and Sageev) and the work of Kahn and Markovic.
