Feynman integrals on functionals of the exponential type with polynomial degree / A. K. Kravtseva. //Vestnik Moskovskogo Universiteta. Seriya 1. Matematika. Mekhanika. 2012. № 6. P. 35-38. [Moscow Univ. Math. Bulletin. Vol. 67, N 6, 2012.].
The concept of Feynman integral in a sense of analytic continuation in the space of complex operators is considered. The existence of the integral is proved and its representation in the form of Gaussian integral is obtained for the case when the dominant term of the integrand is an exponent of polynominal.
Key words: Feynman integral, analytic continuation, Gaussian integral.
