Symmetry analysis and exact solutions of modified Brans-Dicke cosmological equations
Metin Arik, Mikhail B. Sheftel
We perform a symmetry analysis of modified Brans-Dicke cosmological equations and present exact solutions. We discuss how the solutions may help to build models of cosmology where,…

Anti-self-dual Riemannian metrics without Killing vectors, can they be realized on K3?
A. A. Malykh, Y. Nutku, M. B. Sheftel
Explicit Riemannian metrics with Euclidean signature and anti-self dual curvature that do not admit any Killing vectors are presented. The metric and the Riemann curvature scalars…
