Functional integrals in field theory
Soviet Physics Journal, 1990Chronological vacuum mean quantum fields are constructed as states in appropriate commutative tensor algebras, which permits representing their generating functionals as Fourier transforms of measures in spaces of classical fields. These measures belong to a broader class than the functional integrals ordinarily applied in quantum field theory.

Divergent Integrals in Renormalizable Field Theories
Physical Review, 1951The proofs of the renormalization of the theories of scalar and pseudoscalar mesons in scalar interaction with nucleons and with the electromagnetic field, given previously by the author, depended on a certain subtraction procedure. A general proof is here given that this subtraction procedure, when applied to a divergent integral in the $S$ matrix of ...

Field theories for multiple integrals
Journal of Mathematical Sciences, 2011New constructions of fields of extremals for multiple integrals and new versions of the Legendre–Weyl–Caratheodory transform are introduced. The connection and the curvature of fiber bundles on which multiple integrals are defined are calculated.

An Integrated Experiment in Field Theory
International Journal of Electrical Engineering & Education, 1989The various means available for the solution of field problems are reviewed and the solutions for a simple problem, that of the fringing field between the pole and armature of an electric machine, obtained using three methods; direct field plotting, Schwartz-Christoffel transformation and finite elements are presented.

Integral equations for meson field theory
Il Nuovo Cimento, 1957A covariant method of approximating the nucleon Green’s functionS′F is described, in terms of the solution of a connected sequence of linear integral equations. Explicit expressions for the matrix elements for processes involving only one real nucleon are derived by formal functional differentiation ofS′F with respect to external boson fields.

Integrable Quantum Field Theories
2009Abstract An integrable quantum field theory is characterized by an infinite number of conserved charges. In classical mechanics, the existence of a sufficient number of integrals of motion allows us to pass from the initial coordinates and momenta to the angle-action variables, thus finding the exact solution of the equation of motion by
