Events for 02/10/2020 from all calendars
Geometry Seminar
Time: 3:00PM - 4:00PM
Location: BLOC 628
Speaker: Yordanka Kovacheva , University of Maryland
Title: Explicit expression of the Suslin-Voevodsky's isomorphism for quasi-projective variety
Abstract: The Suslin-Voevodsky isomorphism relates finite etale covers of varieties with singular (Suslin) homology of varieties. I would give an explicit way to calculate this isomorphism in terms of functions on curves using Artin reciprocity and Kummer/Weil pairing. I will also give a geometric interpretation of the Weil pairing and relate the Tame and Weil symbols.

Title: Prime number theory--from GL(2) to GL(1)
Abstract: In this talk, I will explain how to use the Fourier expansion for the non-holomorphic Eisenstein series to show that the zeta function is non-vanishing on the 1-line.

Title: Measuring a sponge: how to formulate the isoperimetric problem in fractals
Abstract: The yearly budget of a ranch owner allows him to purchase one mile of fence to delimit a piece of land for the cattle to graze. What shape will provide the largest possible space for the cattle? This question is known as the isoperimetric problem, which consists in finding among all sets with the same perimeter the one that maximizes its area. The problem can be posed in any dimension, and in the usual Euclidean space its solution is known to be the circle or, more generally, a ball. But what if our ambient space is rather porous, like a sponge or a lung, something "fractal"? To formulate the isoperimetric problem we need good notions of area and perimeter, but the standard Euclidean ones become useless here. So, how can we measure the area and the perimeter of a piece of sponge? In this talk we will present the Hausdorff measure and outline a newly developed concept of perimeter as the natural candidates to make sensible measurements in fractal sets.
