Four-dimentional Gradient Shrinking Solitons with Positive Isotropic Curvature
Abstract
We show that a four-dimensional complete gradient shrinking Ricci soliton with positive isotropic curvature is either a quotient of S4 or a quotient of S3 cross R. This gives a clean classification result removing the earlier additional assumptions in [13] by Wallach and the second author.
