Abstract

We construct a new family of skein exact triangles for link Floer homology. The skein triples are described by a triple of rational tangles (R0,R1,R2n+1)(R_0,R_1,R_{2n+1}), where R0R_0 is the trivial tangle and RkR_k is obtained from it by applying kk positive half-twists. We also set up an appropriate framework for potential construction of further skein exact triangles corresponding to arbitrary triples of rational tangles.
