Abstract

We revisit the derivation of Knizhnik-Zamolodchikov equations in the case of nonsemisimple categories of modules of a superalgebra in the case of the generic affne level and representations parameters. A proof of existence of asymptotic solutions and their properties for the superalgebra gl(11)gl(1|1) gives a basis for the proof of existence associator which satisfy braided tensor categories requirements. Braided tensor category structure of Uh(gl(11))U_h(gl(1|1)) quantum algebra calculated, and the tensor product ring is shown to be isomorphic to gl(11)gl(1|1) ring, for the same generic relations between the level and parameters of modules. We review the proof of Drinfeld-Kohno theorem for non-semisimple category of modules suggested by Geer and show that it remains valid for the superalgebra gl(11)gl(1|1). Examples of logarithmic solutions of KZ equations are also presented.
