Exact Solutions of the Field Equations for Empty Space in the Nash Gravitational Theory
(Journal article; Peer reviewed, 2017-02)John Nash has proposed a new theory of gravity. We define a Nash-tensor equal to the curvature tensor appearing in the Nash field equations for empty space, and calculate its components for two cases: 1. A static, spherically ... -
Universal spacetimes in four dimensions
(Journal article; Peer reviewed, 2017-10)Universal spacetimes are exact solutions to all higher-order theories of gravity. We study these spacetimes in four dimensions and provide necessary and sufficient conditions for universality for all Petrov types except ...
