The norm of the Fourier transform on compact or discrete abelian groups

Mokshay Madiman, Peng Xu

We calculate the norm of the Fourier operator from $L^{p} (X)$ to $L^{q} (X^)$ when $X$ is an infinite locally compact abelian group that is, furthermore, compact or discrete. This…

Irreducible $p$ -modular representations of unramified $U (2, 1)$

Ramla Abdellatif, Peng Xu

Let $E / F$ be a unramified quadratic extension of non-archimedean local fields of odd characteristic $p$ , and $G$ be the unramified unitary group $U (2, 1) (E / F)$ . For an irreducible…

A Solution to Time-Varying Markov Decision Processes

Lantao Liu, Gaurav S. Sukhatme

We consider a decision-making problem where the environment varies both in space and time. Such problems arise naturally when considering e.g., the navigation of an underwater robo…

Forward and Reverse Entropy Power Inequalities in Convex Geometry

Mokshay Madiman, James Melbourne, Peng Xu

The entropy power inequality, which plays a fundamental role in information theory and probability, may be seen as an analogue of the Brunn-Minkowski inequality. Motivated by this…
