Cohomogeneity one shrinking Ricci solitons: an analytic and numerical study

We use analytical and numerical methods to investigate the equations for cohomogeneity one shrinking gradient Ricci solitons.

Resumo:We use analytical and numerical methods to investigate the equations for cohomogeneity one shrinking gradient Ricci solitons. We show the existence of a winding number for this system around the subvariety of phase space corresponding to Einstein solutions and obtain some estimates for it. We prove a non-existence result for certain orbit types, analogous to that of Böhm in the Einstein case. We also carry out numerical investigations for selected orbit types.
