Geometric methods for constructing cosmological solutions for EYMH systems in two measure, f(R) and massive gravity theories

Rajpoot, Subhash; Vacaru, Sergiu I. (Singapur : World Scientific Publishing Co. Pte. Ltd., 2018)

A brief summary of the anholonomic frame deformation method, AFDM, for generating exact solutions with generic off-diagonal metrics and generalized nonlinear connections in modified gravity theories, MGTs, is presented. ...
Locally anisotropic cosmological systems in modified two measure and massive gravity theories

Vacaru, Sergiu I. (Singapur : World Scientific Publishing Co. Pte. Ltd., 2018)

We outline a geometric method of constructing generic off-diagonal and diagonal cosmological solutions of effective Einstein equations modeling modified gravity theories with two non-Riemannian volume forms and associated ...
Off-diagonal wormhole and black hole deformations and dark energy in two measure/bi-metric modified gravity theories

Gheorghiu, Tamara; Vacaru, Olivia; Vacaru, Sergiu I. (Singapur : World Scientific Publishing Co. Pte. Ltd., 2018)

We find general parameterizations for generic off-diagonal spacetime metrics and matter sources in general relativity (GR) and two measure/bi-metric modified gravity theories, MGTs, when the field equations decouple with ...
