Abstract
The study of the configurational statistical mechanics of polymers in elongational flows requires the evaluation of quadratic path integrals . Here we present a new technique for the evaluation of such path inte grals; the method relies on Ito excursion theory and the Ray-Knight th eorem from probability theory. In addition to providing a powerful com putational method in standard cases, the method generalizes to deal wi th quadratic path integrals for branching processes.
