THE BRST SYMMETRY OF AFFINE LIE SUPERALGEBRAS AND NONCRITICAL STRINGS
/ Authors
/ Abstract
The topological field theories associated with affine Lie superalgebras are constructed. Their BRST symmetry is characterized by a Kazama algebra containing spin 1, 2 and 3 operators and closes linearly. Under this symmetry all operators are grouped into BRST doublets. The relation between the models constructed and noncritical string theories is explored.
