D2-brane within coset approach

Abstract

In this notes, we derive the component on-shell action of the space-filling D2-brane, i.e. N = 1, d = 3 supersymmetric Born-Infeld action within the nonlinear realization approach. The Bianchi identity admits direct covariantization with respect to the broken N = 1, d = 3 supersymmetry. In the corresponding on-shell component action all fermionic terms combine into covariant, with respect to broken supersymmetry, objects: covariant derivatives and fierbein and therefore the D2-brane component action has very simple form. Similarly to the cases of p-branes, it mimics the bosonic Born-Infeld action.
