Abstract
The purpose of this article is to study gradient Yamabe solitons on top of warped product manifolds. First we prove triviality results in the case of a bounded warping function on a noncompact base and then, for compact base. In order to provide nontrivial examples, we consider the base conformal to a semi-Euclidean space, which is invariant under the action of a translation group, and then we characterize steady solitons. We use this method to give infinitely many explicit examples of complete steady gradient Yamabe solitons.
