"Ricci flow beyond non-negative curvature conditions"

We generalize most of the known Ricci flow invariant non-negative curvature conditions to less restrictive negative bounds that remain sufficiently controlled for a short time.

Yiu-Tung Poon, Iowa State University

"(p,q) Matricial Range and Quantum Information Science"

Monday, October 23, 2017 — 4:00 PM EDT

Damien Roy, University of Ottawa

"Diophantine curiosities"

Tuesday, October 24, 2017 — 11:00 AM EDT

Michael Viscardi, University of California, Berkeley

"Quantum cohomology and 3D mirror symmetry"

Tuesday, October 24, 2017 — 4:00 PM EDT

Levon Haykazyan, Department of Pure Mathematics, University of Waterloo

"Introduction to Positive Logic II"

We continue our investigation of positive logic. I will define a new notion of the space of types and I will convince you that it is the right notion.

"Branching Processes, Martingales, Kingman’s Subadditive Ergodic Theorem, and some applications, Part IV: Kingman’s Subadditive Ergodic Theorem"

And now for something completely different. We leave Galton-Watson processes behind and talk a bit about Birkhoff’s Ergodic Theorem and Fekete’s Lemma. The latter states that an/n converges if an is a subadditive sequence and Kingman’s subadditive ergodic theorem provides a dynamical / random analogue.

Leah Duffett, Department of Pure Mathematics, University of Waterloo

"Horned spheres and Schoenflies Theorem"

Thursday, October 26, 2017 — 1:30 PM EDT

Shaoming Guo, Indiana University Bloomington

"Parsell-Vinogradov systems in higher dimensions"

I will present a few results on counting the numbers of integer solutions of Parsell-Vinogradov systems in higher dimensions. A few techniques from harmonic analysis are crucial in our approach. They are Brascamp-Lieb inequalities, multi-linear Kakeya inequalities, induction on scales, etc.

Justin Laverdure, Department of Pure Mathematics, University of Waterloo

"A finite pointed group with no finite basis (part 2)"

We'll continue to go over the construction of Roger Bryant. Hopefully, we'll finally see the group P, and argue that every (n-1)-generated subalgebra of Q_n is in HSP(P).
