Abstract:
A system of Kirkwood–Salzburg type equations is obtained for the coefficient functions of
the S matrix in the Euclidean region. The existence of solutions of the equations for the coefficient functions in the case of an infinite volume is proved for models of a real scalar field
with bounded nonlinear Lagrangians. A study is made of the analogy between Euclidean quanturn
field theory and statistical mechanics.
