Fixed points, saddle points and universality

TL;DR

This paper discusses how the presence of multiple fixed points in models can lead to violations of universality, challenging previous assumptions in the field.

Contribution

It highlights the potential breakdown of universality due to multiple fixed points, providing new insights into model behavior.

Findings

Universality can be violated by models with several fixed points.

Fixed points significantly influence model universality.

The study emphasizes the need to consider fixed points in theoretical analyses.

Abstract

It is pointed out that the universality might seriously be violated by models with several fixed points.
