Abstract

A procedure commonly used to construct metrics of positive or non-negative sectional curvature is the Cheeger deformation. The aim of this project is to base a generalization of this deformation, tracing its parallel with geometric analysis, in order to obtain obstruction or/and sufficient conditions for positive/nonnegative sectional curvature on principal bundles and other families of manifolds. It is also intended to study the existence of metrics with prescribed scalar curvature and Einstein metrics.
