The geometry of spacetime forms the very foundation of modern gravitational theory, where the elegant interplay between curvature and matter is described by Einstein’s field equations. In this ...

In this paper, we introduce a new type of curvature tensor named 𝓗-curvature tensor of type (1, 3) which is a linear combination of conformal and projective curvature tensors. First we deduce some ...

General Relativity reinterprets the force of gravity not as a traditional force but as a manifestation of the curvature of spacetime. Its formulation rests on a rigorous mathematical framework built ...

We consider gradient Ricci solitons on multiply warped product manifolds. We find the necessary and sucient conditions for multiply warped product manifolds to be gradient Ricci solitons. U. C. De, M.

When the theory of relativity appeared in the early 1900s, it upended centuries of science and gave physicists a new understanding of space and time. Isaac Newton saw space and time as fixed, but in ...

The theory of relativity describes two connected scientific theories developed by the physicist Albert Einstein: special relativity and general relativity. Collectively, relativity is the idea the ...
