Let X ( ) (ds) be an R d -valued homogeneous independently scattered random measure over R having as the distribution of X ( ) ((t; t + 1)). Let f(s) be a nonrandom measurable function on an open interval (a; b) where 1 6 a < b 6 1. The improper stochastic integral R b a+ f(s)X ( ) (ds) is studied. Its distribution f( ) denes a mapping from to an innitely divisible distribution on R d . Three modications (compensated, essential, and symmetrized) and absolute denabilit y are considered. After their domains are characterized, necessary and sucien t conditions for the domains to be very large (or very small) in various senses are given. The concept of the dual in the class of purely non-Gaussian innitely divisible distributions on R d is introduced and employed in studying some examples. The -measure of function f is introduced and whether determines f is discussed. Related transformations of L evy measures are also studied.
