Elliptic curves, modular forms, Hida families

R. Sujatha (Univ. British Columbia)

Abstract: Iwasawa theory provides a unifying strand that allows for a study of the Galois representations arising from elliptic curves and modular forms. The invariants arising from this study provides useful information on concrete problems like the study of rational points of elliptic curves. In this talk, we shall explain how some of these techniques can be extended to study Iwasawa theory of Hida families over non-commutative $p$-adic Lie extensions.

Acylindrically hyperbolic groups and small cancellation quotients

Michael Hull (University of Illinois at Chicago)

Abstract: We will discuss the class of acylindrically hyperbolic groups, a generalization of hyperbolic and relatively hyperbolic groups which includes mapping class groups, $Out(F_n)$ and many other examples. In particular, we will discuss certain generalizations of small cancellation theory to the class of acylindrically hyperbolic groups and the properties and applications of the associated quotient groups. A video recording of this talk can be found at http://gear.math.illinois.edu/events/Geometry-Groups-Dynamics-GEAR-Seminar.html

Two Problems on Building a Geometrical MOOC

Shiya Liu and George Francis   [email] (UIUC)

Abstract: This past summer, Shiya Liu and I worked on two hurdles to overcome before we can build a mathematical MOOC. One is a better way than multiple choice questions for automatic assessment and the second is on the automatic assessment of geometrical constructions in the hyperbolic plane. We will report on our progress. This is the first session of an irregularly scheduled seminar. If you wish to speak in this seminar please contact gfrancis@illinois.edu

Motives and Birational Geometry

R. Sujatha (University of British Columbia)

Abstract: The theory of motives has been a strong inspiring force for mathematical research in the last few decades. We shall discuss a categorical approach to the construction of birational motives and its implications for study of functors that are birational in nature. This is joint work with Bruno Kahn.
