What is On the formulation of D = 11 supergravity and the composite nature of its three-form gauge field about?

The underlying gauge group structure of the D = 11 Cremmer-Julia-Scherk supergravity becomes manifest when its three-form field A 3 is expressed through a set of one-form gauge fields, B a 1 a 2 1 , B a 1 ÁÁÁa 5 1 , g 1a , and E a , w a . These are associated with the generators of the elements of a family of enlarged supersymmetry algebras Ẽð528j32þ32Þ ðsÞ parametrized by a real number s. We study in detail the composite structure of A 3 extending previous results by DÕAuria and Fre ́, stress the equivalence of the above problem to the trivialization of a standard supersymmetry algebra E ð11j32Þ cohomology four-cocycle on the enlarged Ẽð528j32þ32Þ ðsÞ superalgebras, and discuss its possible dynamical consequences. To this aim we consider the properties of the first order supergravity action with a composite A 3 field and find the set of extra gauge symmetries that guarantee that the field theoretical degrees of freedom of the theory remain the same as with a fundamental A 3 . The extra gauge symmetries are also present in the so-called rheonomic treatment of the first order D = 11 supergravity action when A 3 is composite. Our considerations on the composite structure of A 3 prov
