Linearization coefficients of Bessel polynomials
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…
On powers of Stieltjes moment sequences, II
Christian Berg
We consider the set of Stieltjes moment sequences, for which every positive power is again a Stieltjes moment sequence, we and prove an integral representation of the logarithm of…
Integral representation of some functions related to the Gamma function
Christian Berg
We prove that the functions Phi(x)=[Gamma(x+1)]^{1/x}(1+1/x)^x/x and log Phi(x) are Stieltjes transforms.
The Chen-Rubin conjecture in a continuous setting
Henrik L. Pedersen, Christian Berg
We study the median in the Gamma distribution as a function of the parameter. Using methods from complex analysis we show that the derivative of the median is less than 1 and we th…
