Kenneth Onuma, Department of Pure Mathematics, University of Waterloo

In this talk, I will define the following notions: transitive subalgebras, d-irreducible subalgebras and (k,m)-transitive subalgebras of linear operators on a vector space. I will give some examples and prove a structure theorem for minimal (k,m)-transitive subalgebras of linear operators on a vector space.

Ross Willard, Department of Pure Mathematics, University Waterloo

“Varieties with a difference term. I”

In a series of two or three lectures, I will describe the class of varieties (of algebras) which have a difference term.

Laurent Marcoux, Department of Pure Mathematics, University of Waterloo

“Paratransitive algebras of operators”

A collection A of linear operators acting on a finite-dimensional vector space V is said to be transitiveif for any vector y ∈ V

“Nash groups”

The category of Nash manifolds lies strictly in between that of smooth real algebraic varieties and that of real analytic manifolds.

“Applications of the Smooth Theorem and Cyclic Terms”

In this final lecture covering the paper ”Absorbing subalgebras, cyclic terms, and the constraint satisfaction problem” by Barto and Kozik, I will give two appli

“The Kadison-Singer Problem: conclusion”

This will complete the proof of the main theorem. This is the last talk in the series.

“Shapiro’s Lemma”

Given groups H ⊆ G and an H-module M, we have an associated G

“The Stokes groupoids”

In joint work with Marco Gualtieri and Songhao Li, we construct Lie groupoids that serve as the universal domains for the parallel transport of meromorphic connections over Riemann surfaces.

Yu-Ru Liu, Department of Pure Mathematics, University of Waterloo

“Equidistribution of polynomial sequences in function fields”

We prove a function field analog of Weyl’s classical theorem on equidistribution of polynomial sequences.

“Homomorphism Dichotomy for Finite Oriented Trees”

The well-known CSP Dichotomy Conjecture, due to Feder and Vardi (1998) states that, for any finite relational template A, the homomorphism problem HOM(A) is either solvable in polynomial time or NP-complete.
