Representability conditions by Grassmann integration [PDF]
Advances in Theoretical and Mathematical Physics, 2015 Representability conditions on the one- and two-particle density matrix for fermion systems are formulated by means of Grassmann integrals. A positivity condition for a certain kind of Grassmann integral is established which, in turn, induces the well-known G-, P- and Q-Conditions of quantum chemistry by an appropriate choice of the integrand ...

Generalized Feynman integrals via conditional Feynman integrals.
Michigan Mathematical Journal, 1993 The paper is a continuing exercise by the authors to arrive at the most generalized version of Feynman integrals studied by Cameron and his collaborators. The starting point is the Wiener integral \(\int_{C_ 0[0,T)} F(\lambda^{-1/2} Z(x,.)+\xi) (\lambda^{-1/2} Z(x,T)+\xi)m(dx)\) where \(Z\) is the Gaussian process \(Z(x,t)=\int^ t_ 0 h(s)dx(s)\) with \(

Operator-valued Feynman integrals via conditional Feynman integrals [PDF]
Pacific Journal of Mathematics, 1990 The authors define a ``conditional integral of Feynman'' which plays the same role as the conditional expectation with regard to the Wiener integral. Then they use a conditional integral to calculate the Feynman integrals (kind of operational integral of Feynman) of different functions. The proofs are carefully developed.

Mixed problem with integral condition for the hyperbolic equation
Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2011 In this paper we consider a nonlocal problem with integral condition of the first kind. Existence and uniqueness of a solution of this problem are proved. The proof is based on a priori estimates and auxiliary problem method.
