Minkowski superspaces and superstrings as almost real complex supermanifolds
Stockholm University, Faculty of Science, Department of Mathematics.
2012 (English)In: Theoretical and mathematical physics, ISSN 0040-5779, E-ISSN 1573-9333, Vol. 173, no 3, 1687-1708 p.Article in journal (Refereed) Published
Abstract [en]

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.
