Abstract
We propose the another, in principe nonperturbative, method of the evaluation of the Wiener functional integral for term in the action. All infinite summations in the results are proven to be convergent. We finf the "generalized" Gelfand -- Yaglom differential equation implying the functional integral in the continuum limit.
