Abstract

Consider the multiplicative semigroup M (S )of all probability distribution fu ctions on subsets S of R 2 .This structure corresponds to the coordi atewise maximum of S -valued independe t random vectors. We provide a wide class of possible territories S ,where in spite of the lack of the u it element in M (S ),there is a Khinchine-type decomposition.I case M (S )has a unit element,we characterize the subsets S with the property that there is a decompositio in M (S ).
