Eric Bergshoeff, Joaquim Gomis, Paul K. Townsend

TL;DR
This paper demonstrates that M-brane intersections in M-theory are represented within the worldvolume supersymmetry algebras through p-form charges, providing a new algebraic perspective on brane interactions.
Contribution
It reveals that M-brane intersections are encoded in the worldvolume supersymmetry algebras via p-form charges, extending the understanding of brane dynamics.
Findings
Intersections are represented by p-form charges in worldvolume algebras.
Triple intersections correspond to double intersection algebras with eight supercharges.
Provides an algebraic framework for understanding M-brane intersections.
Abstract
It is known that the M-branes of M-theory correspond to p-form charges in the D=11 spacetime supersymmetry algebra. Here we show that their intersections are encoded in the p-form charges of their worldvolume supersymmetry algebras. Triple intersections are encoded in double intersection worldvolume algebras with eight supercharges.
