A mathematically rigorous treatment of the antisymmetrized geminal power AGP model is given. The model is advocated as an extremely flexible tool for studying a wide variety of fermion systems, characterized by a single Slater determinant, on the one hand, or Yang's most highly correlated wave funct

The analytic properties in the energy variables of the one-and two-particle propagator are investigated on the basis of an exact solution of an AV-particle model with a simplified and separable two-body potential, \* This work is supported in part through funds provided by the Atomic Energy Commissi
## Abstract We introduce a lattice model for a static and isotropic system of relativistic fermions. An action principle is formulated, which describes a particleβparticle interaction of all fermions. The model is designed specifically for a numerical analysis of the nonlinear interaction, which is
A nonlinear extension of the generalized Maxwell model is proposed as a constitutive equation for viscoelastic fluids. Expressions for complex-viscosity, oscillatory normal stresses, non-Newtonian viscosity and two normal stress differences are given in terms of four parameters. Comparison is made w
