| Abstrakt: | If the arguments of a function G: Rd ? R1are taken as quadratic functional defined on a space C of continuous functions, we obtain a functional G: C ? R1.We give a formula for computing analytic Feynman integrals of such functionals. We also propose a method of approximate computation of sequential Feynman integrals based on replacing the kernel of an integral operator by a degenerate kernel. |
