Robustness of CSC Sasaki existence under the join operation
Open access0 citations
Abstract
The main purpose of this work is to explore the existence of constant scalar curvature Sasaki metrics in the Sasaki cone of the join of two regular Sasaki manifolds, M 1 and M 2 . Furthermore, we consider some cases of continuous families of extremal Sasaki twins.
