Title: One-time signatures from Generalized discrete logarithms

Speaker: David Jao Affiliation: University of Waterloo Room: MC 5501

Abstract:

Thursday, June 23, 2016 — 3:30 PM to 4:30 PM EDT

Title Minimally non-ideal clutters

Tuesday, June 21, 2016 — 4:00 PM to 4:30 PM EDT

Title: Spectra of Discrete Quantum Walks

Tuesday, June 21, 2016 — 3:30 PM to 4:00 PM EDT

Title: Intersecting Families of Perfect Matchings

Tuesday, June 21, 2016 — 2:30 PM to 3:30 PM EDT

Title: Group-labelled graphs

Tuesday, June 14, 2016 — 4:30 PM to 5:30 PM EDT

Title: Pseudolinear drawings of graphs

Tuesday, June 14, 2016 — 3:30 PM to 4:30 PM EDT

Title: Graphs and Faces

Speaker: Chris Godsil Affiliation: University of Waterloo Room: MC 6486

Abstract: Each eigenspace of the adjacency matrix of a graph gives
rise to a polytope. I will discvuss the relations between properties
of the graph and the geometry of the polytope.

Tuesday, June 14, 2016 — 2:30 PM to 3:30 PM EDT

Title: Coffman-Sethi conjecture in multiprocessor scheduling

Tuesday, June 7, 2016 — 3:30 PM to 4:30 PM EDT

Title: Quantum walk, uniform mixing algebraic numbers

Speaker: Chris Godsil Affiliation: University of Waterloo Room: MC 6486

Abstract: We use number theory to derive necessary conditions for
local uniform mixing on bipartite graphs.

Tuesday, June 7, 2016 — 2:30 PM to 4:30 PM EDT

Title: Post-quantum cryptography

Speaker: David Jao Affiliation: University of Waterloo Room: MC 6486

Abstract:

Thursday, June 2, 2016 — 3:30 PM to 4:30 PM EDT

Title: On almost all matroids

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

Abstract: I will (for real this time) discuss a recent paper of Pendavingh and Van der Pol that resolved several natural, long-standing conjectures about the properties of almost all matroids. Namely, for some m that is polylogarithmic in n, almost all matroids on n elements are m-connected and have the rank-m self-dual uniform matroid as a minor.
