Convexity of Momentum Maps: A Topological Analysis
Wolfgang Rump, Jenny Santoso
The Local-to-Global-Principle used in the proof of convexity theorems for momentum maps has been extracted as a statement of pure topology enriched with a structure of convexity. W…

A General Local-to-Global Principle for Convexity of Momentum Maps
Wolfgang Rump, Jenny Santoso
We extend the Local-to-Global-Principle used in the proof of convexity theorems for momentum maps to not necessarily closed maps whose target space carries a convexity structure wh…
