Pagliacci, Michela (2002) A simple-product formula for certain Kazhdan-Lusztig R-polynomials. UNSPECIFIED. (Unpublished)
Abstract
We obtain a simple product formula for the Kazhdan-Lusztig R-polynomials, Ru,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<l<j. These results are proved combinatorially and include the main result of [7], Sect.5, as special case.
