Noncommutative -integrators and stochastic differential equations in

David A. Jekel, Todd A. Kemp, Evangelos A. Nikitopoulos

We propose a new framework for noncommutative stochastic integration in , inspired by Bichteler's notion of -integrators, that massively generalizes our previous theory o…

Eigen-Spike Emergence and Quadratic Equivalents for Conjugate Kernels on Nonlinearly Separable Data

Collin Cranston, Zhichao Wang, Todd Kemp +1

Recent work in random matrix theory (RMT) has developed the notion of deterministic equivalents: typically linear surrogate models that approximate the spectral behavior of large n…

Eigenvalues of Brownian Motions on

Tatiana Brailovskaya, Nicholas A. Cook, Todd Kemp +1

We prove that the empirical law of eigenvalues of Brownian motion on the Lie Group converges almost surely to a deterministic probability measure, chara…

Matrix Random Walks and the Lima Bean Law

Bruce K. Driver, Brian C. Hall, Ching Wei Ho +4

A matrix random walk is a stochastic process of the form where are independent ``step'' matrices in . With the right en…

Bias and Division in the Free World

Larry Goldstein, Todd Kemp

Sampling bias is a foundational concept in statistics; associated bias transforms, such as size bias, have come to play important roles in probability theory of late. The first aut…

A martingale approach to noncommutative stochastic calculus

David A. Jekel, Todd A. Kemp, Evangelos A. Nikitopoulos

We present a new approach to noncommutative stochastic calculus that is, like the classical theory, based primarily on the martingale property. Using this approach, we introduce a…
