PRE F ACE

The 1988 Conference "Probability Measures on Groups" was designed, in deviation from the previous meetings on the subject, as a forum on which the interplay between structural probability theory and seemingly quite distant topics of pure and applied mathematics were to be discussed and documented. T'he various interrelations were made explicit in the expository talks presented on special

There has been a wide range of topics with some emphasis on convolution semigroups of measures, their potential theory and harmonic analysis. While at the preceding conferences on probability measures on groups the basic structure was mainly a group or a semigroup, the recent development emphasizes more general
