A bivariate infinitely divisible distribution with exponential and Mittag–Leffler marginals

چکیده
We introduce a bivariate distribution supported on the first quadrant with exponential, and heavy tailed Mittag–Leffer, marginal distributions. Although this distribution belongs to the class of geometric operator stable laws, it is a rather special case that does not follow their general theory. Our results include the joint density and distribution function, Laplace transform, conditional distributions, joint moments, and tail behavior. We also establish infinite divisibility and stability properties of this model, and clarify its connections with operator stable and geometric operator stable laws. © 2009 Elsevier B.V.

Infinitely Divisibility of Solutions of Some Semi-stable Integro-differential Equations and Exponential Functionals of Lévy Processes
0 (1 ∧ x2) ν(dx) < +∞, are uniquely determined by the distribution of a spectrally negative infinitely divisible random variable, with characteristic exponent ψ. L(α,ψ,γ) is known to be the infinitesimal generator of a 1 α -semi-stable Feller semigroup on R+, which has been introduced by Lamperti [18]. The functions are expressed in terms of a new family of power series which includes, for inst...
متن کاملA Generalization of the Results of Pillai
In a recent article Pillai (1990, Ann. Inst. Statist. Math., 42, 157-161) showed that the distribution 1-E~(-x~), 0 < c~ _< 1; 0 _< x, where E~(x) is the Mittag-Lettter function, is infinitely divisible and geometrically infinitely divisible. He also clarified the relation between this distribution and a stable distribution. In the present paper, we generalize his results by using Bernstein fun...

In this paper we give generalization of Opial-type inequalities by using generalized fractional integral operator involving generalized Mittag–Leffler function. We deduce some results which already have been proved. Also we consider n -exponential convexity of some non-negative differences of inequalities involving Mittag-Leffler function and deduce their exponential convexity and log-convexity.
