Abstract:
For the Minkowski superspace and superstrings, we define and compute a circumcised analogue of the Nijenhuis tensor, the obstruction to the integrability of an almost real–complex structure. The Nijenhuis tensor vanishes identically only if the superstring superdimension is $1|1$ and, moreover, the superstring is endowed with a contact structure. We also show that all real forms of Grassmann algebras are isomorphic, although they are defined by obviously different anti-involutions.
Keywords:
real supermanifold, complex supermanifold, Nijenhuis tensor, string theory, nonholomorphic distribution, Kähler supermanifold, hyper-Kähler supermanifold.
