Christian Berg, Christophe Vignat
We prove positivity results about linearization and connection coefficients for Bessel polynomials. The proof is based on a recursion formula and explicit formulas for the coeffici…

Stochastic invertible mappings between power law and Gaussian probability distributions
C. Vignat, A. Plastino
We construct "stochastic mappings" between power law probability distributions (PD's) and Gaussian ones. To a given vector , Gaussian distributed (respectively , exponentiall…
