In cosmology, Gurzadyan theorem, proved by Vahe Gurzadyan,[1] states the most general functional form for the force satisfying the condition of identity of the gravity of the sphere and of a point mass located in the sphere's center. This theorem thus refers to the first statement of Isaac Newton’s [2]shell theorem (the identity mentioned above) but not the second one, namely, the absence of gravitational force inside a shell.[3]
The theorem had entered and its importance for cosmology outlined in several papers [4][5] as well as in shell theorem.
