The Kontsevich integral and quantized Lie superalgebras
Given a finite dimensional representation of a semisimple Lie algebra
there are two ways of constructing link invariants: 1) quantum group
invariants using the R-matrix, 2) the Kontsevich universal link
invariant followed by the Lie algebra based weight system. Le and
Murakami showed that these two link invariants are the same. These
constructions can be generalized to some classes of Lie
superalgebras. In this paper we show that constructions 1) and 2) give
the same invariants for the Lie superalgebras of type A-G. We use this
result to investigate the Links-Gould invariant. We also give a
positive answer to a conjecture of Patureau-Mirand's concerning
invariants arising from the Lie superalgebra D(2,1;alpha).
