Generalized quasi-conformal curvature tensor (ω-tensor) has the flavor of conformal, conharmonic, concircular, projective, m-projective, W1-curvature, W2-curvature and W4-curvature tensors. In the present paper we have investigated the nature of Rie

Sultana–Dyer black hole, obtained by a time-dependent conformal transformation of Schwarzschild black hole, is an exact solution of general relativity in spherical symmetry. This paper provides the investigation of geometrical properties of the Sul

The hypersurface of a space is one of the most important objects in a space. Many authors studied the various geometric aspects of hypersurfaces in a space form. The notion of conformal flatness is one of the most primitive concepts in differential g
