Abstract

This study focuses on a spacetime admitting quasi-constant curvature tensor. Several properties of this spacetime are found. Also, such a spacetime satisfying a critical point equation is analyzed. Considering some special situations of this spacetime, some novel properties of this spacetime are examined. Some remarkable results about these subjects are obtained.
