An analytic approach to the finite R-transform
Octavio Arizmendi, Katsunori Fujie
We revisit Marcus' finite free analogue of Voiculescu -transform from an analytic viewpoint. By relating the finite free Fourier transform to the Laplace transform, we study the…

Octavio Arizmendi, Andrew Campbell, Katsunori Fujie
A result of Hoskins and Steinerberger [Int. Math. Res. Not., (13):9784-9809, 2022] states that repeatedly differentiating a random polynomials with independent and identically dist…

Finite Free Convolution: Infinitesimal Distributions
Octavio Arizmendi, Daniel Perales, Josue Vazquez-Becerra
Finite-free additive and multiplicative convolutions are operations on the set of polynomials with real roots, introduced independently by Szegö and Walsh in the 1920s. These oper…
