Gradient almost Ricci solitons on multiply warped product manifolds

In this paper, we investigate multiply warped product manifold =B₁䃑 F₁₁䃒 F₂₁䃓 ₁䂷 Fₘ\ as a gradient almost Ricci soliton. Taking bᵢ=b for 1 i m lets us to deduce that potential field depends on B. With this idea we also get a rigidity result and show that base is a generalized quasi-Einstein manifold if b is conformal.
