Feynman integral formulae and fundamental solutions of decomposable evolution operators
N. Ortner, P. Wagner Institute of Mathematics and Geometry University of Innsbruck, Austria
Abstract:
The fundamental solutions of products of quasihyperbolic partial differential operators are represented by definite integrals making use of generalized versions of Feynman's parametric integrals. The formulae deduced are applied to derive the fundamental solutions of products of transport, heat, and Klein–Gordon operators, respectively.
Keywords:
fundamental solutions, hyperbolic partial differential operators, Klein–Gordon operators, heat diffusion, evolution operators.
