A Hilbert--Mumford criterion for generalised Monge--Amp\`ere equations

Differential Geometry 2025-04-10 v1 Algebraic Geometry

Abstract

We give a new numerical criterion in the spirit of GIT for existence of solutions to inverse Hessian equations, including in particular the J-equation. Our criterion is formulated in terms of stability of pairs in the sense of Paul. To that end, we build on previous work of the author with Dervan, and generalise a result of Zhang, proving isometry between generalised Chow line bundles and mixed Deligne pairings.
