Deformed Double Current Algebras, Matrix Extended ${\mathcal{W}}_{\infty }$ Algebras, Coproducts, and Intertwiners from the M2-M5 Intersection

Davide Gaiotto, Miroslav Rapčák, Yehao Zhou

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 c…
