Idea Broad idea The Green-Schwarz action functional is an action functional for a sigma-model that describes the propagation of a fundamental super pp-brane Σ\Sigma in a super spacetime supermanifold. For p=0p = 0 this is the Green-Schwarz superparticle. For p=1p = 1 this is the Green-Schwarz superstring (Green-Schwarz 84) For p=2p =2 this is the Green-Schwarz supermembrane (Bergshoeff-Sezgin-Town
