Abstract

The purpose of this paper is to characterise $\eta$-Ricci-Yamabe solitons in paracontact geometry. Specifically, we investigate para-Kenmotsu manifolds admitting $\eta$-Ricci-Yamabe solitons and three-dimensional para-Kenmotsu manifolds satisfying gradient $\eta$-Ricci-Yamabe solitons. We also study para-Sasakian manifolds and para-cosymplectic manifolds obeying $\eta$-Ricci-Yamabe solitons and gradient $\eta$-Ricci-Yamabe solitons, respectively. As a consequence we obtain several interesting corollaries. Finally, we provide an example of $\eta$-Ricci-Yamabe solitons in a para-Kenmotsu manifold.
