Stability of measures on Kähler manifolds. (English) Zbl 1355.53072

Summary: Let \((M, \omega)\) be a Kähler manifold and let \(K\) be a compact group that acts on \(M\) in a Hamiltonian fashion. We study the action of \(K^{\mathbb{C}}\) on probability measures on \(M\). First of all we identify an abstract setting for the momentum mapping and give numerical criteria for stability, semi-stability and polystability. Next we apply this setting to the action of \(K^{\mathbb{C}}\) on measures. We get various stability criteria for measures on Kähler manifolds. The same circle of ideas gives a very general surjectivity result for a map originally studied by Hersch and Bourguignon-Li-Yau.
