Abstract

This article presents a study on $D$-homothetically deformed $K$-contact manifolds. If a contact metric obtained by a $D$-homothetic deformation of $M$ is a $\eta$-Ricci-Yamabe soliton with point-wise collinear then $M$ reduces to $\eta$-Einstein have been established. Furthermore, we characterise an $\eta$-Ricci-Yamabe soliton, and two more solitons, on Ricci flat, concircularly flat, $M$-projectively flat $K$-contact manifold under $D$-homothetic deformation.
