In 1980, Lusztig introduced the periodic Kazhdan–Lusztig polynomials, which are conjectured to have important information about the characters of irreducible modules of a reductive group over a field of positive characteristic, and also about those of an affine Kac–Moody algebra at the critical level. The periodic Kazhdan–Lusztig polynomials can be computed by using another family of polynomials, called the periodicR-polynomials. In this paper, we prove a (closed) combinatorial formula expressing periodicR-polynomials in terms of the “doubled” Bruhat graph associated to a finite Weyl group and a finite root system.
