DOI: 10.1142/s0218271818500475
Abstract: In this paper, we have analyzed the role of a viable f(R,T) model, i.e. f(R,T) = R + αR2 + γRn + λT, while exploring the unstable regions of cylindrically symmetric gravitational source, where, R… read more here.

DOI: 10.3390/sym15030754
Abstract: We search for exact analytical solutions of spherically symmetric dissipative fluid distributions satisfying the vanishing expansion condition (vanishing expansion scalar Θ). To accomplish this, we shall impose additional restrictions allowing integration of the field equations.… read more here.
