Asymptotic root distribution of polynomials under repeated polar differentiation
Daniel Perales, Zhiyuan Yang
Given a sequence of real rooted polynomials with a fixed asymptotic root distribution, we study the asymptotic root distribution of the repeated polar derivativ…
Second order free cumulants: product, commutator, and anti-commutator
Daniel Munoz George, Daniel Perales
Given two second order free random variables and , we study the second order free cumulants of their product , their commutator , and their anti-commutator $ab+ba…
Zeros of orthogonal little q-Jacobi polynomials: interlacing and monotonicity
Andrei Martinez-Finkelshtein, Rafael Morales, Daniel Perales
We investigate the distribution of zeros of the little q-Jacobi polynomials and related q-hypergeometric families. We prove that the zeros of these orthogonal polynomials exhibit s…
Even Hypergeometric Polynomials and Finite Free Commutators
Jacob Campbell, Rafael Morales, Daniel Perales
We study in detail the class of even polynomials and their behavior with respect to finite free convolutions. To this end, we use some specific hypergeometric polynomials and a var…
