标题： The Small Field Parabolic Flow for Bosonic Many-body Models: Part 3 - Nonperturbatively Small Errors

摘要： 本文是对一个程序的贡献，该程序旨在观察在低温下三维晶格上的弱相互作用多玻色子系统中的对称性破缺。 它是对“抛物线流”的分析的一部分，该流表现出“墨西哥帽”势阱的形成。 在这里，我们提供了一些论点，这些论点表明但并未完全证明，“小场”近似与完整模型之间的差异是非微扰的小。 显示英文摘要

摘要： This paper is a contribution to a program to see symmetry breaking in a weakly interacting many Boson system on a three dimensional lattice at low temperature. It is part of an analysis of the "parabolic flow" which exhibits the formation of a "Mexican hat" potential well. Here we provide arguments that suggest, but do not completey prove, that the difference between the "small field" approximation and the full model is nonperturbatively small.
