Tutte's Distinguished Lecture Series
The very successful Tutte's 100th Distinguished Lecture Series has now completed. That success has led to a Tutte Distinguished Lecture once per term. The next lecture will happen in the Spring term.
*Recordings of occurred talks are all available on C&O's YouTube Channel.
Grad Studies: Fall 2020 applications now open
New Deadline: February 1, '20
The Canadian Mathematical Society (CMS) has named Luke Postle as the recipient of the 2021 Coxeter-James Prize for his work in graph theory.
Jodie Wallis (BMath ’93) was a natural fit for Operations Research at the Faculty of Mathematics. “I liked how Operations Research brought together different disciplines and applied directly to business problems,” she affirmed. “That process of taking a problem, considering multiple layers of solutions, and ending up with something that’s elegant and workable in the real world was appealing to me.”
C&O professor David Gosset has published a paper "Classical algorithms for quantum mean values" in Nature Physics.
Title: The embezzlement of entanglement and its applications
Speaker: | Debbie Leung |
Affliation: | University of Waterloo |
Zoom: | Please email Emma Watson |
Abstract:
Embezzlement of entanglement is the (impossible) task of producing an entangled state from a product state via a local change of basis, when a suitable *catalytic* entangled state is available.
The possibility to approximate this task was first observed by van Dam and Hayden in 2002. Since then, the phenomenon is found to play crucial roles in many aspects of quantum information theory. In this talk, we will discuss aspects of embezzlement and some applications (such as why quantum correlations do not form a closed set, and why there are nonlocal games that cannot be played optimally with a finite amount of entanglement, and why additive quantities cannot be more than asymptotically continuous).
Title: Lexicographic products, wreath products, and generalisations
Speaker: | Joy Morris |
Affiliation: | University of Lethbridge |
Zoom: | Contact Soffia Arnadottir |
Abstract:
I will present a history and overview of some of the work that has been done on the lexicographic product of graphs, and related generalisations. The focus of my talk will be on the automorphism groups of such graphs, and the relationship to the wreath product of permutation groups.
Title: Equivalences of Wilson loop diagrams
Speaker: | Karen Yeats |
Affiliation: | University of Waterloo |
Zoom: | Contact Karen Yeats |
Abstract:
I will talk about Wilson loop diagrams, explain a bit about what they are, and some of the combinatorial questions that come out of them, with a focus on when they are equivalent. This is joint work with Susama Agarwala and Zee Fryer.

The University of Waterloo acknowledges that much of our work takes place on the traditional territory of the Neutral, Anishinaabeg and Haudenosaunee peoples. Our main campus is situated on the Haldimand Tract, the land granted to the Six Nations that includes six miles on each side of the Grand River. Our active work toward reconciliation takes place across our campuses through research, learning, teaching, and community building, and is centralized within our Indigenous Initiatives Office.
