MMP for Generalized Pairs on K\"ahler 3-folds

Algebraic Geometry 2025-03-07 v2 Complex Variables

Abstract

In this article we define generalized pairs (X,B+β)(X, B+\boldsymbol{\beta}) where XX is an analytic variety and β\boldsymbol{\beta} is a b-(1,1) current. We then prove that almost all standard results of the MMP hold in this generality for compact K\"ahler varieties of dim X3X\leq 3. More specifically, we prove the cone theorem, existence of flips, existence of log terminal models, log canonical models and Mori fiber spaces, the geography of log canonical and log terminal models, etc.

Comments

Throughly revised, definition of generalized pairs is updated, statements and proofs of some lemmas are revised. Statements of main theorem are mostly unaffected (except Theorem 1.4 and 1.5), but theirs proofs are revised. 52 pages, comments are welcome
