Book
Potential Theory on Locally Compact Abelian Groups
Christian Berg,Gunnar Forst +1 more
TL;DR: In this article, the potential theory for Transient Convolution Semigroups and Transient Convergence Lemmas and potential Theoretic Principles are presented. But they do not address the problem of generating potential kernels.
Book
Harmonic Analysis on Semigroups: Theory of Positive Definite and Related Functions
TL;DR: In this paper, the authors present general results on Positive and Negative Definite Matrices and Kernels on Abelian Semigroups and define simple properties of positive and negative Definite Kernels.
Journal ArticleDOI
Integral representation of some functions related to the Gamma function
TL;DR: In this paper, it was shown that the functions Θ(Θ(x) = [Gamma (x + 1)]^{1/x} (1 + 1/x)^x /x) and Θ (Θ (x, Θ) = Θ((Θ + 1)/x)) are Stieltjes transforms.
Journal ArticleDOI
Density questions in the classical theory of moments
TL;DR: In this paper, the conditions générales d'utilisation (http://www.numdam.org/conditions) are defined, i.e., toute utilisation commerciale ou impression systématique is constitutive d'une infraction pénale.
