Title: Graph Reconstruction

Speaker: Cathy Wang
Affiliation:  University of Waterloo
Room: MC 6486

Abstract: The graph reconstruction conjecture by Kelly and Ulam states that all graphs on at least three vertices are determined by their one-vertex deleted subgraphs, up to isomorphism.

Title: Finding Independent Transversals Efficiently

Speaker: Alessandra Graf
Affiliation: University of Waterloo
Room: MC 5479

Abstract: Let G be a graph whose vertex set is partitioned into classes V1,..., Vm. An independent transversal of G with respect to (V1,...,Vm) is an independent set {v1,...,vm} in G such that vi is in Vi for each i.

Title: Combinatorics in Particle Interactions

Speaker: Freddy Cachazo
Affiliation: Perimeter Institute
Room: MC 5501

Abstract:

The main approach for testing physical theories of particles is via scattering experiments. The traditional approach for computing theoretical predictions uses Feynman diagrams.
