Computer Science/Discrete Mathematics Seminar I

Graphs, CSPs and Codes
Madhu Sudan
11:00am|Simonyi 101 and Remote Access

A sparsification of a structure, with respect to a class of queries, produces a compressed representation of the structure while answering every query in the class approximately correctly. The seminal example of sparsification is "graph...

Truth and Beauty: Bombieri's Mathematical Gardens

G-functions ,Q-points, and Unlikely Intersections
Jonathan Pila
4:00pm|Simonyi 101 and Remote Access

I will describe a problem of unlikely intersections in a product of modular curves, tracing the problem itself and the tools for some results through the work of Enrico.

Truth and Beauty: Bombieri's Mathematical Gardens

On Effectivity for Integral Points on Some Curves of Genus 2
Umberto Zannier
2:40pm|Simonyi 101 and Remote Access

Most effective results for integral points on affine curves use the works of Baker or Bombieri on Diophantine approximation by S-units. Still, no completely general result is known already in genus 2. I will briefly present some recent work with...

Condensed Learning Seminar

K-Theory Satisfies Nisnevich Descent
Longke Tang
2:30pm|Princeton University, Fine Hall 314

Review the notion of cd-structure for a Grothendieck topology and explain how it helps check the sheaf conditions. Introduce and discuss the Nisnevich topology for schemes and analytic adic spaces; in particular, discuss their equivalent...

  • Yan-Lung Leon Li :Equivariant Lagrangian Correspondence and a Conjecture of Teleman

    It has been a continuing interest, often with profound importance, in understanding the geometric and topological relationship between a Hamiltonian G-manifold Y and...

Joint PU/IAS Number Theory

Infinite Orbits In Certain Elliptic Surfaces, Ax Schanuel, and Ramification In The Legendre Family
Umberto Zannier
4:30pm|*Princeton University, Fine 214*

Motivated by work of Cantat-Dujardin, we study orbits by translations in K3 surfaces with two elliptic fibrations. We prove in particular that all orbits are infinite away from a proper Zariski-closed subset.

Among the tools, beyond the Pila-Wilkie...

Joint PU/IAS Number Theory

Ax-Schanuel and Exceptional Integrability
Jonathan Pila
3:00pm|*Princeton University, Fine 214*

In joint work with Jacob Tsimerman we study when the primitive of a given algebraic function can be constructed using primitives from some given finite set of algebraic functions, their inverses, algebraic functions, and composition. When the given...
