P、NP、NP完全和NP困难等问题集的欧拉图(Euler diagram)。左侧在P ≠ NP的假设下有效,而右侧在P = NP的假设下有效。 图源:Behnam Esfahbod 另一位研究人员,来自麻省理工学院的Rahul Ilango(拉胡尔·伊兰戈),一直致力于以多种方式证明MCSP的NP完全性,将MCSP的更简单和更复杂的版本视为解决主要问题的切入点。

We discuss three applications of NJL- and PNJL-like models to assess aspects of the QCD phase diagram: First, we study the effect of mesonic correlations on the pressure below and above the finite temperature phase transition within a non-local PNJL model beyond the mean-field approximation....
