A Simple Product Formula for Certain Kazhdan-Lusztig<i>R</i>-Polynomials
ABSTRACT We obtain a simple product formula for the Kazhdan-Lusztig R -polynomials, R u,v ( q ) indexed by permutations “ u , v” in the case that v is obtained from u , applying two transpositions ( i , j) and ( k , l), for i < k …
