WebbIn a 2015 preprint, Brosnan and Chow prove the Shareshian–Wachs conjecture (also proved independently by Guay–Paquet using combinatorial methods ) by showing a remarkable relationship between the Betti numbers of different Hessenberg varieties; a key ingredient in their approach is a certain family of Hessenberg varieties, the (cohomology ...

Webb1 okt. 2024 · Since multipermutations without any plateau are Smirnov words, our result generalizes a γ-positivity result due to Linusson, Shareshian and Wachs in this special case. Interestingly, our second action on multipermutations applies also to Stirling multipermutations and results in another combinatorial expansion for their partial γ … WebbRhoades, Serrano, Shareshian, Wachs. Suppose S is a set and let C be a finite cyclic group acting on S. If g 2C, we let Sg = ft 2S : gt = tg and o(g) = order of g in C. We also let!d = primitive dth root of unity. Finally, suppose we are given f(q) 2R[q], a polynomial in q. grace baptist church crestline ohio
