This paper investigates wormhole solutions of spherically symmetric spacetime via Noether
symmetry approach in f (R, T) gravity. For this purpose, we choose f (R, T) models …

This paper investigates the geometry of static traversable wormhole through Noether
symmetry approach in f (R) gravity. We take perfect fluid distribution and formulate symmetry …

In D-dimensional spherically symmetric f (R) gravity there are three unknown functions to be
determined from the fourth order differential equations. It is shown that the system …

We present the properties of relativistic, inviscid, low angular momentum, advective
accretion flow in af (R) gravity theory that satisfactorily mimics the asymptotically flat vacuum …

A number of recent observations have suggested that the Einstein's theory of general
relativity may not be the ultimate theory of gravity. The f (R) gravity model with R being the …

Abstract theory is a modification of Einstein's general relativity which has provided many
interesting results in cosmology and astrophysics. To derive a black hole solution in this …

We investigate the problem of static and spherically symmetric solutions in the Starobinsky
gravity model. By extending the Lichnerowicz and Israel theorems, William Nelson has …

We investigate cylindrically symmetric spacetimes in the context of f (R) gravity. We firstly
attain conformal symmetry of the cylindrically symmetric spacetime. We obtain solutions to …

The elliptic boundary value problem governing the steady electrical heating of a conductor
of heat and electricity, the so-called thermistor problem,∇·(σ (u)∇ ϕ)= 0 in Ω ϕ= ϕ b on …

Two problems of the general theory of relativity and a problem in the electrical heating of
conductors (the so-called thermistor problem), lead to the same set of partial differential …
