Db. Fairlie et J. Nuyts, 2-INDEX GENERALIZATIONS OF SUPERCONFORMAL ALGEBRAS, Journal of physics. A, mathematical and general, 29(20), 1996, pp. 511-515
The superconformal algebras of Ademollo et al are generalized to a mul
ti-index form. The structure obtained is similar to the Moyal bracket
analogue of the Neveu-Schwarz algebra.
