Multivariate Weibull and Pareto Distributions in Hilbert Space

Two general multivariate distributions in a real separable Hilbert space H are introduced in this article, one is multivariate Weibull distribution (denoted by GMW^H), the other is multivariate Pareto distribution (denoted by GMP^H). They are more general than the existing references. Some characterization theorems of the GMW^H and GMP^H via an intensively monotone operator are proved. The limiting behaviors and the interrelationship between the GMW and GMP in Euclidean space are also studied.
