Convergence of Empirical Measures for i.i.d. samples in $W^{- α, p}$

Gautam Iyer, Raghavendra Venkatraman

Given $N$ i.i.d. samples from a probability measure $μ$ on $R^{d}$ , we study the rate of convergence of the empirical measure $μ_{N} \to μ$ in the negative Sobolev space $W^{-…

Exponentially mixing flows with slow enhanced dissipation

William Cooperman, Gautam Iyer, Keefer Rowan +1

Consider a passive scalar which is advected by an incompressible flow $u$ and has small molecular diffusivity $κ$ . Previous results show that if $u$ is exponentially mixing and $C^…

Residual Diffusivity for Expanding Bernoulli Maps

William Cooperman, Gautam Iyer, James Nolen

Consider a discrete time Markov process $X^{ε}$ on $R^{d}$ that makes a deterministic jump based on its current location, and then takes a small Gaussian step of variance $ε^{2}$ …
