Title: Announcing new Reading Group this term on the topic of "Entropy and Counting"

Speaker: Various/TBD Affiliation: University of Waterloo Room: MC 6486

Abstract:

A new Reading Group will be starting this term on the topic of "Entropy and Counting". The talks will take place weekly on Tuesdays from 2:00 p.m. to 3:00 p.m. in MC 6486 starting on Jan 22th.

Tuesday, January 22, 2019 — 2:00 PM EST

Title: Introduction to Entropy and Counting

Speaker:  Richard Lang Affiliation: University of Waterloo Room: MC 6486

Abstract: In the first talk of our reading group, we introduce the notion of entropy and derive some of its basic properties.

Wednesday, January 23, 2019 — 3:30 PM EST

Title: Induced Poset Saturation

Speaker: Bill Kay Affilliation: Ryerson University Room: MC 6486

Abstract: In Graph Theory, we say that a graph G is H saturated if G contains no copy of H as a subgraph,

Title: Additive Approximation of Chromatic Number in Apex-minor-free Graphs

Speaker: Justin Toth Affiliation: University of Waterloo Room: MC 5479

Abstract: In this talk we will see a t+3 additive approximation to the chromatic number for t-apex-minor-free

Friday, January 25, 2019 — 3:30 PM EST

Title: Convex Optimization Problems in Domain-Driven Form

Speaker: Mehdi Karimi Affiliation: University of Waterloo Room: MC 5501

Abstract:

In this talk, we introduce the Domain-Driven form for convex optimization problems and show how general it is by several examples; including LP, SDP, geometric and entropy programming, and quantum entropy optimization.

Tuesday, January 29, 2019 — 2:00 PM EST

Title: Applications of the entropy method

Speaker: Michelle Delcourt Affiliation: University of Waterloo Room: MC 6486

Abstract: In the second talk of our reading group on entropy and counting.

Wednesday, January 30, 2019 — 3:30 PM EST

Title: Fractional coloring with local demands

Speaker: Tom Kelly Affiliation: University of Waterloo Room: MC 6486

Abstract: In a fractional coloring, vertices of a graph are assigned subsets of the $[0, 1]$-interval such that adjacent vertices receive disjoint subsets. 

Thursday, January 31, 2019 — 1:30 PM EST

Title: Quantum Walks on Oriented Graphs

Speaker: Sabrina Lato Affiliation: University of Waterloo Room: MC 6486

Abstract: A quantum walk on a graph is defined based on a Hermitian matrix associated with the graph, such as the adjacency matrix.
