On gradient $\ddot{I}$-Einstein solitons with Bach tensor radially nonnegative

Maria Andrade, Valter Borges, Hiuri Reis

In this paper, we study $n$-dimensional gradient $\ddot{I}$-Einstein solitons whose Bach tensor is radially nonnegative. Under this assumption, we show that such $\ddot{I}$-Einstein solitons a…
