On triviality and scalar curvature estimation of gradient h-almost Yamabe solitons

In this study we have explored gradient $h$-almost Yamabe solitons on both compact and complete non-compact Riemannian manifolds.

We have established several sufficient conditions for the triviality of such solitons with respect to integral inequalities involving the scalar curvature and the soliton function.

In this regard, we have acquired scalar curvature estimation under certain $L^2$-integrability conditions, and defined signal of the function $h$.

Our results extend and refine former works on almost and $h$-almost Yamabe solitons, and characterize the geometric structures of generalized Yamabe solitons.
