Let p be a prime, and let RG(p) denote the set of equivalence classes of radically graded finite dimensional quasi-Hopf algebras over C, whose radical has codimension p. In [EG1],[EG2] we completely describe the set RG(p). Namely, we show that for p > 2, RG(p) consists of the quasi-Hopf algebras A(q) constructed in [G] for each primitive root of unity q of order p, the Andruskiewitsch-Schneider Hopf algebras [AS1], and semisimple quasi-Hopf algebras H+(p) and H−(p) of dimension p; on the other… CONTINUE READING
