We find conditions on the ten parameters of the Poincare Gauge Theory of Gravity which are necessary for solutions with an asymptotically anti-de Sitter metric and asymptotically constant Riemann-Cartan curvature or asymptotically constant torsion

The positive total energy test is applied to the Poincaré Gauge Theory of gravity. Both the asymptotically flat and asymptotically constant negative curvature case are considered. The test shows that in either case, the theory with generic values fo

In searching for rotonless solutions to the full equations of the Poincare gauge theory of gravitation under spherically symmetric conditions, we found a unique set of lagrangians for the theory in which the absence of rotons will give the Schwarzsch

A class of theories with gravity treated as a gauge theory for the Poincare group has been developed principally by Hehl l ) and Hayashi and Shirafuj?) and their respective associates. These theories are very much in accord with contemporary fundamen

It was shown recently by Havas that for a Newtonian system of three particles there exists a class of exact solutions which is nonplanar, such that the particles revolve with constant angular velocity in circular orbits in parallel planes. Such motio

By using the de Rham-Yano-Bochner lemma on harmonic tensor fields in a compact orientable manifold, we show that the extra dimensions in eleven-dimensional simple supergravity will he Ricci-flat if they are compact.

Dirac's constraint algorithm is adapted to find the canonical Hamiltonian formulation of the one-parameter teleparallel theory of gravity which is supposed to have some problematical gauge properties. The analysis verifies that the theory has the str

This investigation explores the current sheath surrounding an exploding copper wire in vacuum. Rogovski coils are used to map the current sheath. The results are plotted as a function of time and radius. Soon after the transplosion of the wire, the c
