Modular Transformations and Invariants in the Context of Fractional Level Affine sl(2|1;C)

Published 1999-09-10, updated 2000-01-10Version 2

The modular transformation properties of admissible characters of the affine superalgebra sl(2|1;C) at fractional level k=1/u-1, u=2,3,... are presented. All modular invariants for u=2 and u=3 are calculated explicitly and an A-series and D-series of modular invariants emerge.
