摘要

We study the algebraic structures which govern the deformation of supersymmetric intersections of M2 and M5 branes. The universal algebras on M2 and M5 branes are deformed double current algebra of $\mathfrak {gl}_K$ ${gl}_{K}$ and $\mathfrak {gl}_K$ ${gl}_{K}$ -extended $\mathcal {W}_{\infty }$ $W_{\infty}$ -algebra respectively. We give a new presentation of the deformed double current algebra of $\mathfrak {gl}_K$ ${gl}_{K}$ , and we give a rigorous mathematical construction of the $\mathfrak {gl}_K$ ${gl}_{K}$ -extended $\mathcal {W}_{\infty }$ $W_{\infty}$ -algebra. A new presentation of the affine Yangian of $\mathfrak {gl}_K$ ${gl}_{K}$ is also obtained. We construct various coproducts of these algebras, which are expected to encode the fusions of defects in twisted M-theory. The matrix extended Miura operators are identified as intertwiners in certain bimodules of these algebras.
