Léonard Ferdinand, Razvan Gurau, Carlos I. Perez-Sanchez, Fabien Vignes-Tourneret

AI总结:

本研究针对四次O(N)-向量模型,采用圈顶点展开方法证明其配分函数与连通关联函数的1/N展开沿实轴具有Borel可和性,且该性质在复平面类心形区域内对耦合常数一致成立。

摘要:

我们研究一个四次O(N)-向量模型。利用圈顶点展开(Loop Vertex Expansion),我们证明了该模型的配分函数及连通关联函数沿实轴的1/N展开具有Borel可和性。只要耦合常数属于复平面上避开负实轴的类心形区域,该Borel可和性对耦合常数一致成立。

英文摘要:

We consider a quartic O(N)-vector model. Using the Loop Vertex Expansion, we prove the Borel summability in 1/N along the real axis of the partition function and of the connected correlations of the model. The Borel summability holds uniformly in the coupling constant, as long as the latter belongs to a cardioid like domain of the complex plane, avoiding the negative real axis.
