Abstract
In this research paper, we determine the Ricci-Yamabe soliton on a perfect fluid space-time with a torse-forming vector field. Besides this, we evaluate a specific situation when the potential vector field zeta is of the gradient type, we deduce a Poisson and a Liouville equation from the soliton equation. In addition, we explore some harmonic significance of gamma-Ricci-Yamabe soliton on perfect fluid spacetime with a harmonic potential function psi. Finally, we discuss necessary and sufficient conditions for the 1-form gamma, which is the g-dual of the vector field zeta on a perfect fluid spacetime to be a solution for the Schrodinger-Ricci equation.
