Abstract We construct a new class of ( p , q )-extended Poincare supergravity theories in 2+1 dimensions as Chern-Simons theories of supersymmetry algebras with both central and automorphism charges. The new theories have the advantage that they are limits of corresponding ( p , q ) adS supergravity theories and, for not too large a value of N = p + q , that they have a natural formulation in terms of off-shell superfields, in which context the distinction between theories having the same value… Expand
