Compactly supported radial basis functions as probability density functions

Sergio Díaz-Elbal, Andrei Martínez-Finkelshtein, Darío Ramos-López

Compactly Supported Radial Basis Functions (CS-RBFs) are a fundamental tool in multivariate approximation theory. However, their use in statistics and probability modeling remains…

Interlacing and monotonicity of zeros of Angelesco-Jacobi polynomials

Andrei Martinez-Finkelshtein, Rafael Morales

Information about the behavior of zeros of classical families of multiple or Hermite-Padé orthogonal polynomials as functions of the intrinsic parameters of the family is scarce. W…

Real roots of hypergeometric polynomials via finite free convolution

Andrei Martinez-Finkelshtein, Rafael Morales, Daniel Perales

We examine two binary operations on the set of algebraic polynomials, known as multiplicative and additive finite free convolutions, specifically in the context of hypergeometric p…
