Plane Wave Solutions of Weakened Field Equations in a Plane Symmetric Space-time-II

Abstract

In this paper, we propose to obtain the Z=(t/z)-type plane gravitational waves in a set of five vacuum weakened equations in the space-time introduced by us having plane symmetry in the sense of Taub [Ann.Math.53,472 (1951)]. These vacuum field equations has been suggested as alternatives to the Einstein vacuum field equations of general relativity. Furthermore the physical significance of modified gravitational waves for the space-time is obtained.
