"Non-linear fractals and Hausdorff measure"
Analysis Seminar
Robert Xu Yang, Department of Pure Mathematics, University of Waterloo
"Interpolation Sets in Harmonic Analysis"
Many classical harmonic analysis results are based on 'Lacunary or Hadamard sets'. Weierstrass used Hadamard sequences to build the first example of nowhere differentiable continuous function. Hadamard sets also inspired the classical Hadamard gap theorem and the Riesz product measure, which is an example of a continuous measure whose Fourier coefficients do not vanish at infinity.
Baker-DeMarco Learning Seminar
Yoav Len, Department of Combinatorics & Optimization, University of Waterloo
"Berkovich spaces"
Berkovich analytic spaces are a slick way for "filling the holes" in varieties defined over non-Archimedean fields. In the talk, I will introduce the analytification construction, and make the previous sentence more precise. I will explicitly construct the Berkovich line, and explain how to find the analytification of curves of higher genus. The talk will mostly be informal, and focus on results and constructions rather than precise proofs.

Graduate Student Colloquium
Nick Rollick, Department of Pure Mathematics, University of Waterloo
"Mistakes don't matter: Getting the message without getting the message"
Number Theory Seminar
François Seguin, Queen's University
"Prime divisors of sparse values of cyclotomic polynomials"
We will be presenting a result about the largest prime divisor of cyclotomic polynomials evaluated at a specific integer.
MC 5417
Algebraic Geometry Learning Seminar
Christopher Hawthorne, Department of Pure Mathematics, University of Waterloo
"Elimination theory and closed embeddings"
We finish chapter 7 with a discussion of quantifier elimination and the fundamental theorem of elimination theory; we then begin to study closed embeddings of schemes.

Postdoctoral Seminar
Matthew Harrison-Trainor, Department of Pure Mathematics, University of Waterloo
"How to know when you've proved the best possible characterization or classification"
Algebra Seminar
Liron Speyer, University of Virginia
"Decomposable Specht modules"
I will give a brief survey of the study of decomposable Specht modules for the symmetric group and its Hecke algebra, which includes results of Murphy, Dodge and Fayers, and myself. I will then report on an ongoing project with Louise Sutton, in which we are studying decomposable Specht modules for the Hecke algebra of type B indexed by 'bihooks'.
