A Field Theory with Curvature and Anticurvature

Abstract EN

The present work is an attempt to construct a unified field theory in a space with curvature and anticurvature, the PAP-space.

The theory is derived from an action principle and a Lagrangian density using a symmetric linear parameterized connection.

Three different methods are used to explore physical contents of the theory obtained.

Poisson’s equations for both material and charge distributions are obtained, as special cases, from the field equations of the theory.

The theory is a pure geometric one in the sense that material distribution, charge distribution, gravitational and electromagnetic potentials, and other physical quantities are defined in terms of pure geometric objects of the structure used.

In the case of pure gravity in free space, the spherical symmetric solution of the field equations gives the Schwarzschild exterior field.

The weak equivalence principle is respected only in the case of pure gravity in free space; otherwise it is violated.
