Title: The Chvátal-Gomory procedure for integer SDPs with applications in combinatorial optimization

Speaker: Frank de Meijer
Affiliation: Tilburg University
Location: MC 5501 or please contact Emma Watson for Zoom link

Abstract:

Semidefinite programs under the presence of integrality constraints are known as integer semidefinite programs (ISDPs). Since the combination of integrality and positive semidefiniteness leads to matrices that are highly structured, ISDPs have applications in several fields, including architecture and combinatorial optimization.

Tuesday, May 24, 2022 — 9:00 AM to Friday, May 27, 2022 — 4:30 PM EDT

A celebration of Goulden and Jackson's combined 90 years of insight and inspiration that have shaped the fields of algebraic and combinatorial enumeration.

Title: On Donuts and Quasigraphic matroids

Speaker: Peter Nelson
Affiliation: University of Waterloo
Room: MC 5417

Abstract:

Quasigraphic matroids are graph-like objects that give a common generalization of lift and frame matroids. Donuts are edible topological surfaces. I will talk about a surprising link between these two types of object, assuming no prior knowledge of quasigraphic matroids or donuts.

Title: Faster Algorithms for Isogeny Problems using Torsion Point Images. 

Speaker: Dinesh Valluri
Affiliation: University of Waterloo
Attend: Contact Jesse Elliott

Abstract:

In this talk, we will discuss cryptanalysis of some SIDH-type protocols due to Christophe Petit: https://eprint.iacr.org/2017/571.pdf. While finding isogenies between supersingular elliptic curves remains computationally hard to solve, knowledge of images of specific torsion points by the unknown isogeny helps build faster attacks.

Title: Early Work

Speaker: Ian Goulden
Affiliation: University of Waterloo
Location: QNC 0101 or please contact Emma Watson for Zoom link

Abstract:

I will talk briefly and informally about my work in the last century.


Title: At It and In It

Speaker: David Jackson
Affiliation: University of Waterloo
Location: QNC 0101 or please contact Emma Watson for Zoom link

Abstract:

I have selected seven Research Themes to talk about very briefly and informally.  They are reflections upon key moments and surprising revelations over the past forty years.
