In this study, we introduce new characterizations for warped-twisted product
manifolds. We investigate gradient Riemann, gradient Ricci, gradient Yamabe
solitons on warped-twisted product manifolds and we examine the eect of a gra-
dient soliton on such manifolds to their factor manifolds and we also study the
warped-twisted product quasi-Einstein manifolds.
