The Quantum Cosmological Wavefunction at Very Early Times for a Quadratic Gravity Theory
Simon Davis
The quantum cosmological wavefunction for a quadratic gravity theory derived from the heterotic string effective action is obtained near the inflationary epoch and during the initi…
The quantum theory of a quadratic gravity action for heterotic strings
Simon Davis, Hugh Luckock
The wave function for the quadratic gravity theory derived from the heterotic string effective action is deduced to first order in by solving a perturbed se…
Higher-Derivative Quantum Cosmology
Simon Davis
The quantum cosmology of a higher-derivative derivative gravity theory arising from the heterotic string effective action is reviewed. A new type of Wheeler-DeWitt equation is obta…
The Effect of Higher-Order Curvature Terms on String Quantum Cosmology
Simon Davis, Hugh Luckock
Several new results regarding the quantum cosmology of the quadratic gravity theory derived from the heterotic string effective action are presented. After describing techniques fo…
Scalar Field Theory in Curved Space and the Definition of Momentum
Simon Davis
Some general remarks are made about the quantum theory of scalar fields and the definition of momentum in curved space. Special emphasis is given to field theory in anti-de Sitter…
Symmetric Variations of the Metric and Extrema of the Action for Pure Gravity
Simon Davis
Symmetries of generalized gravitational actions, yielding field equations which typically involve at most second-order derivatives of the metric, are considered. The field equation…
