Sub-Gaussian heat kernel estimates are typical of fractal graphs. We show that sub-Gaussian estimates on graphs follow from a Poincaré inequality, capacity upper bound, and a slow volume growth condition. An important feature of this work is that we...

In this work we examine notions of alignment with respect to a generalized form of Holder's inequality.

Schubert calculus began in the 1880s when Hermann Schubert began asking enumerative questions in geometry, such as how many lines in space are incident to four given lines. Efforts to build a rigorous foundation for these questions led to the...

In this talk, I will present an $L^\infty$-estimate for non-local parabolic SPDEs with measurable jumping kernels, using an improved version of stochastic De Giorgi iteration. Then a priori Holder estimate will be given for solutions of these SPDEs...

Note: This is a work-in-progress seminar talk

The L-Space Conjecture is taking the low-dimensional topology community by storm. It aims to relate seemingly distinct Floer homological, algebraic, and geometric properties of a closed 3-manifold Y. In particular, it predicts a 3-manifold Y isn't...

A video of this event is available on mathtube.org. The number of inversions of a permutation is an important statistic that arises in many contexts, including as the minimum number of simple transpositions needed to express the permutation and...

Dirichlet's theorem on arithmetic progressions states that for any (a,q)=1, there are infinitely many primes congruent to a modulo q. Such a theorem together with Euler's earlier work on the infinitude of primes represents the beginning of the study...

The aim of this event is to offer graduate students in Statistics and Actuarial Science with an opportunity to attend a seminar with accessible talks providing them an introduction to active areas of research in the field. For three students from...

This talk presents joint work with Ed Perkins which can be considered a followup to the paper "Super-Brownian motion and the spatial Lambda-Fleming-Viot process" by Chetwynd-Diggle and Etheridge, Electron. J. Probab. (2018). In that paper the authors...
