Determinantally equivalent nonzero functions
Harry Sapranidis Mantelos
We study the problem raised in [Marco Stevens, Equivalent symmetric kernels of determinantal point processes, RMTA, 10(03):2150027, 2021] concerning the extension of its main resul…

Norm-dependent Lamperti-type MAP representations of stable processes and Brownian motions in the orthant
Andreas E. Kyprianou, Harry S. Mantelos, Victor Rivero
We start by remarking a one-to-one correspondence between self-similar Markov processes (ssMps) on a Banach space and Markov additive processes (MAPs) that is analogous to the well…
