A fixed-point theorem for definably amenable groups

TL;DR

This paper establishes a fixed-point theorem analogue for definably amenable groups, extending classical fixed-point results to a broader class of groups with definable amenability.

Contribution

It introduces a novel fixed-point theorem specifically applicable to definably amenable groups, expanding the theoretical framework.

Findings

Proves a fixed-point theorem for definably amenable groups

Extends classical fixed-point results to new group classes

Provides foundational results for further research in model theory

Abstract

We prove an analogue of the fixed-point theorem for the case of definably amenable groups.
