Abstract
For a given two-dimensional compact oriented surface Σ with boundary, we define invariants with 4 variables for links in Σ×[0, 1]. These invariants restrict to the two-variable HOMFLY polynomials when Σ=D2. Some comments are made about the action of the mapping class group of Σ on these invariants
