Normal curvature of immersed tori of dimension at most $18$

Matteo Raffaelli

We prove that if the $n$ -dimensional torus $T^{n}$ is smoothly immersed in the unit ball $B^{q} \subset R^{q}$ and $n \leq 18$ , then there exists a point at which the spherical aver…

Mixing times of one-sided $k$ -transposition shuffles

Evita Nestoridi, Kenny Peng, Bryan Wong

We study mixing times of the one-sided $k$ -transposition shuffle. We prove that this shuffle mixes relatively slowly, even for $k$ big. Using the recent ``lifting eigenvectors'' te…

Shuffling via sums of Jucys--Murphy Elements

Samira Arfaee, Evita Nestoridi

We consider a family of card shuffles of $n$ cards in which the allowed moves involve transpositions corresponding to the Jucys--Murphy elements of the symmetric group $\{S_m\}_{m…

Limit Profiles for Separation Distance

Peter E. Francis, Evita Nestoridi

This paper studies limit profiles for the separation distance. A limit profile records the limiting shape of the distance to stationarity inside the cutoff window, at times of the…

Limit Profiles for Reversible Markov Chains

Evita Nestoridi, Sam Olesker-Taylor

In a recent breakthrough, Teyssier [Tey20] introduced a new method for approximating the distance from equilibrium of a random walk on a group. He used it to study the limit profil…

Continuity for Limit Profiles of Reversible Markov Chains

Evita Nestoridi

We prove that the limit profile of a sequence of reversible Markov chains exhibiting total variation cutoff is a continuous function, under a computable condition involving the spe…
