In this research article, we estimate the behavior of an imperfect fluid generalized Robertson - Walker spacetime (𝐺𝑅𝑊) in terms of 𝑘-Yamabe soliton with torseforming vector field. Besides this, we evaluate a specific situation when the potential vector filed is of the form of gradient i.e., = grad(Ψ), we extract a Laplace - Poisson equation, and Liouville equation from the quasi 𝑘-Yamabe soliton equation.
