Reducedness conjecture for Kazhdan–Lusztig ideal initial schemes

At least 15 years old · documented by

Let v,w∈Snv,w\in S_n, let Iv,wI_{v,w} be the associated Kazhdan–Lusztig ideal, and let ≺v,w,π\prec_{v,w,\pi} be one of the term orders determined by a generalized antidiagonal permutation π\pi. The initial ideal init≺v,w,πIv,w{\rm init}_{\prec_{v,w,\pi}}I_{v,w} defines a scheme. Reducedness conjecture for Kazhdan–Lusztig ideals. For some π\pi, init≺v,w,πIv,w{\rm init}_{\prec_{v,w,\pi}}I_{v,w} defines a reduced and equidimensional scheme, so the hypothesis and consequently the conclusion of Theorem~ (V) hold. This conjecture is presented as a complement to the paper's main theorem and is part of the proposed degenerations of Kazhdan–Lusztig ideals; the supplied text gives no resolution.
