Rigidez de sólitons de Ricci gradiente com curvatura escalar constante

Abstract

In this work we study the rigidity results obtained in the papper titled "On gradient Ricci solitons with constant scalar curvature" by Fernández-López and Garcia-Río [Proc. Amer. Math. Soc. 114 (2016) 369-373]. They proved that: if the scalar curvature of a gradient Ricci soliton is constant then it is a multiple of the constant of the fundamental equation of the Ricci soliton. This fact was one of the main tools for them to obtain subsequent rigidity results.
