Isometric flows of $G_2$-structures

Differential Geometry 2020-08-18 v1

Abstract

We survey recent progress in the study of flows of isometric G2G_2-structures on 7-dimensional manifolds, that is, flows that preserve the metric, while modifying the G2G_2-structure. In particular, heat flows of isometric G2G_2-structures have been recently studied from several different perspectives, in particular in terms of 33-forms, octonions, vector fields, and geometric structures. We will give an overview of each approach, the results obtained, and compare the different perspectives.
