# Dark energy as a solution of the basic gravitational equation without the cosmological constant

TWMS JOURNAL OF PURE AND APPLIED MATHEMATICS（2022）

Abstract

Based on the analysis of the gravitational equation of a special form that does not contain a cosmological constant, a linear relationship is established between the scalar curvature of space and the density of the mass of matter. For a space with a Friedman-type metric there is a solution that confirms the existence of a dark energy.
