论文摘要
我们研究M弦构型的BPS计数函数（自由能）。我们认为分离的M5贿赂以及它们之间伸展的M2-branes，M5-branes充当域壁插值M2-branes的不同构型。我们在这些配置的自由能中发现递归结构。域壁上的M弦乐自由度是用一对相互作用的超对称WZW模型来解释的。我们还在ABJM理论的玩具模型中计算了M弦的椭圆属，并将其与M理论计算进行了比较。
We study the BPS counting functions (free energies) of the M-string configurations. We consider separated M5-branes along with M2-branes stretched between them, with M5-branes acting as domain walls interpolating different configurations of M2-branes. We find recursive structure in the free energies of these configurations. The M-string degrees of freedom on the domain walls are interpreted in terms of a pair of interacting supersymmetric WZW models. We also compute the elliptic genus of the M-string in a toy model of the ABJM theory and compare it with the M-theory computation.
