Abstract
This work aims to provide some triviality results for complete Cotton solitons under different assumptions like non-positive Ricci curvature, convergence to zero at infinity, polynomial or volume growth, and stochastic completeness. Finally, as an application, we classify the Cotton solitons with additional curative condition to be isometric to a space form of constant sectional curvature or to a Riemannian product \(M^2(c)\times N^1\), where \(N^1={\mathbb {R}}^1\) or \({\mathbb {S}}^1\) for some c.
