Abstract

This note provides an alternative probabilistic approach to the Φ2n theory in dimension 2. The key idea is to study the concentration phenomenon of martingales associated to polynomials of Gaussian variables. This is based on an adaptation of the work of Lacoin-Rhodes-Vargas [3] on the quantum Mabuchi K-energy.

Funding Statement

This work was supported by the ERC grant QFPROBA, No.741487.
