Title: An Introduction to Discrete Quantum Walks

Speaker: Harmony Zhan Affiliation: University of waterloo Room: MC 6486

Abstract:

We will introduce the concept of a discrete quantum walk, prove some of its properties, discuss its relation to different graph structures, and construct interesting walks from these structures such as self-dual embeddings.

Title: An application of graph "recolouring”

Speaker: Ben Moore Affiliation: University of Waterloo Room: MC 5479

Abstract:

I will prove that for any graph G, if there is an edge e such that G-e has less than (k-1)!/2 cycles of length zero mod k, then the chromatic number of G is less or equal to k.
