2D supergravity in p + 1 dimensions Original Research Article

We describe new N-extended 2D supergravities on a (p + 1)-dimensional (bosonic) space. The fundamental objects are moving frame densities that equip each (p + 1)-dimensional point with a 2D “tangent space”. The theory is presented in a [p + 1,2] superspace. For the special case of p = 1 we recover the 2D supergravities in an unusual form. The formalism has been developed with applications to the string-parton picture of D-branes at strong coupling in mind.
