Wiener-regularized path integrals for canonical and spin degrees of freedom

Wiener-regularized path integrals have been introduced by Daubechies and Klauder [1] in the early 1980's in order to provide probabilistic representations of the time-evolution operator for systems with canonical as well as spin degrees of freedom. We will give an introduction to the subject and present in some detail Wiener-regularized path integrals for spin sytems.
