  • Homogeneous Flows, Moduli Spaces and Arithmetic
    CLAY MATHEMATICS INSTITUTE SUMMER SCHOOL 2007 Homogeneous Flows, Moduli Spaces and Arithmetic at the Centro di Ricerca Matematica Designed for graduate students and mathematicians within Ennio De Giorgi, Pisa, Italy five years of their PhD, the program is an introduction to the theory of flows on homogeneous spaces, moduli spaces and their many applications. These flows give concrete examples of dynamical systems with highly interesting behavior and a rich and powerful theory. They are also a source of many interesting problems and conjectures. Furthermore, understanding the dynamics of such a concrete system lends to numerous applications in number theory and geometry regarding equidistributions, diophantine approximations, rational billiards and automorphic forms. The school will consist of three weeks of foundational courses Photo: Peter Adams and one week of mini-courses focusing on more advanced topics.

  • Diagonalizable Flows on Locally Homogeneous Spaces and Number
    Diagonalizable flows on locally homogeneous spaces and number theory Manfred Einsiedler and Elon Lindenstrauss∗ Abstract.We discuss dynamical properties of actions of diagonalizable groups on locally homogeneous spaces, particularly their invariant measures, and present some number theoretic and spectral applications. Entropy plays a key role in the study of theses invariant measures and in the applications. Mathematics Subject Classification (2000). 37D40, 37A45, 11J13, 81Q50 Keywords. invariant measures, locally homogeneous spaces, Littlewood’s conjecture, quantum unique ergodicity, distribution of periodic orbits, ideal classes, entropy. 1. Introduction Flows on locally homogeneous spaces are a special kind of dynamical systems. The ergodic theory and dynamics of these flows are very rich and interesting, and their study has a long and distinguished history. What is more, this study has found numerous applications throughout mathematics. The spaces we consider are of the form Γ\G where G is a locally compact group and Γ a discrete subgroup of G. Typically one takes G to be either a Lie group, a linear algebraic group over a local field, or a product of such. Any subgroup H < G acts on Γ\G and this action is precisely the type of action we will consider here. One of the most important examples which features in numerous number theoretical applications is the space PGL(n, Z)\ PGL(n, R) which can be identified with the space of lattices in Rn up to homothety. Part of the beauty of the subject is that the study of very concrete actions can have meaningful implications. For example, in the late 1980s G.

Woyczyński Case Western Reserve University Universitext is a series of textbooks that presents material from a wide variety of mathematical disciplines at master’s level and beyond. The books, often well class-tested by their author, may have an informal, personal even experimental approach to their subject matter. Some of the most successful and established books in the series have evolved through several editions, always following the evolution of teaching curricula, into very polished texts. Thus as research topics trickle down into graduate-level teaching, first textbooks written for new, cutting-edge courses may make their way into Universitext.

  • On the Iwasawa Invariants of Kato's Zeta Elements for Modular Forms
    ON THE IWASAWA INVARIANTS OF KATO’S ZETA ELEMENTS FOR MODULAR FORMS CHAN-HO KIM, JAEHOON LEE, AND GAUTIER PONSINET Abstract. We study the behavior of the Iwasawa invariants of the Iwasawa modules which appear in Kato’s main conjecture without p-adic L-functions under congruences. It general- izes the work of Greenberg–Vatsal, Emerton–Pollack–Weston, B.D. Kim, Greenberg–Iovita– Pollack, and one of us simultaneously. As a consequence, we establish the propagation of Kato’s main conjecture for modular forms of higher weight at arbitrary good prime under the assumption on the mod p non-vanishing of Kato’s zeta elements. The application to the ± and ♯/♭-Iwasawa theory for modular forms is also discussed. Contents 1. Introduction 1 2. Main results and applications 6 3. “Prime-to-p local” Iwasawa theory 8 4.

Especially, in their ground-breaking work [GV00], Greenberg and Vatsal observed that both algebraic and analytic Iwasawa in- variants of elliptic curves with good ordinary reduction over the cyclotomic Zp-extension Q∞ of Q can be described in terms of the information of the residual representations and the local arXiv:1909.01764v2 [math.NT] 29 Nov 2019 behavior at bad reduction primes under the µ = 0 assumption.

  • Mathematisches Forschungsinstitut Oberwolfach Arithmetic Geometry
    Mathematisches Forschungsinstitut Oberwolfach Report No. 38/2016 DOI: 10.4171/OWR/2016/38 Arithmetic Geometry Organised by Gerd Faltings, Bonn Johan de Jong, New York Peter Scholze, Bonn 7 August – 13 August 2016 Abstract. Arithmetic geometry is at the interface between algebraic geom- etry and number theory, and studies schemes over the ring of integers of number fields, or their p-adic completions. An emphasis of the workshop was on p-adic techniques, but various other aspects including Hodge theory, Arakelov theory and global questions were discussed. Mathematics Subject Classification (2010): 11G99. Introduction by the Organisers The workshop Arithmetic Geometry was well attended by over 50 participants from various backgrounds. It covered a wide range of topics in algebraic geometry and number theory, with some focus on p-adic questions. Using the theory of perfectoid spaces and related techniques, a number of results have been proved in recent years. At the conference, Caraiani, Gabber, Hansen and Liu reported on such results. In particular, Liu explained general p-adic versions of the Riemann–Hilbert and Simpson correspondences, and Caraiani reported on results on the torsion in the cohomology of Shimura varieties. This involved the geometry of the Hodge–Tate period map, which Hansen extended to a general Shimura variety, using the results reported by Liu. Moreover, Gabber proved degeneration of the Hodge spectral sequence for all proper smooth rigid spaces over nonarchimedean fields of characteristic 0, or even in families, by proving a spreading out result for proper rigid spaces to reduce to a recent result in p-adic Hodge theory.

  • L-Invariants of Low Symmetric Powers of Modular Forms and Hida Deformations
    L-invariants of low symmetric powers of modular forms and Hida deformations Robert William Harron A Dissertation Presented to the Faculty of Princeton University in Candidacy for the Degree of Doctor of Philosophy Recommended for Acceptance by the Department of Mathematics Adviser: Andrew Wiles September 2009 c Copyright by Robert William Harron, 2009. All Rights Reserved Abstract We obtain formulae for Greenberg's L-invariant of symmetric square and symmetric sixth power motives attached to p-ordinary modular forms in the vein of theorem 3.18 of [GS93]. For the symmetric square of f, the formula obtained relates the L- invariant to the derivative of the p-adic analytic function interpolating the pth Fourier coefficient (equivalently, the unit root of Frobenius) in the Hida family attached to f. We present a different proof than Hida's, [Hi04], with slightly different assumptions. The symmetric sixth power of f requires a bigger p-adic family. We take advantage of a result of Ramakrishnan{Shahidi ([RS07]) on the symmetric cube lifting to GSp(4)=Q, Hida families on the latter ([TU99] and [Hi02]), as well as results of several authors on the Galois representations attached to automorphic representations of GSp(4)=Q, to compute the L-invariant of the symmetric sixth power of f in terms of the derivatives of the p-adic analytic functions interpolating the eigenvalues of Frobenius in a Hida family on GSp(4)=Q. We must however impose stricter conditions on f in this case. Here, Hida's work (e.g. [Hi07]) does not provide answers as specific as ours.
