چکیده
Abstract We provide a homological construction of unitary simple modules Cherednik and Hecke algebras type A via BGG resolutions, solving conjecture Berkesch–Griffeth–Sam. vastly generalize the its solution to cyclotomic over arbitrary ground fields, calculate Betti numbers Castelnuovo–Mumford regularity certain symmetric linear subspace arrangements.

Permutation Resolutions for Specht Modules of Hecke Algebras
In [BH], a chain complex was constructed in a combinatorial way which conjecturally is a resolution of the (dual of the) integral Specht module for the symmetric group in terms of permutation modules. In this paper we extend the definition of the chain complex to the integral Iwahori Hecke algebra and prove the same partial exactness results that were proved in the symmetric group case.
متن کاملComputing Signatures for Representations of the Hecke and Cherednik Algebras
In this paper, we compute the signatures of the contravariant form on Specht modules for the cyclotomic Hecke algebra and compute the signature character of the contravariant form on the polynomial representation of the rational Cherenik algebra associated toG(r, 1, n).
متن کاملUnitary Representations of Rational Cherednik Algebras
We study unitarity of lowest weight irreducible representations of rational Cherednik algebras. We prove several general results, and use them to determine which lowest weight representations are unitary in a number of cases. In particular, in type A, we give a full description of the unitarity locus (justified in Subsection 5.1 and the appendix written by S. Griffeth), and resolve a question b...
متن کاملBaby Verma Modules for Rational Cherednik Algebras
These are notes for a talk in the MIT-Northeastern Spring 2015 Geometric Representation Theory Seminar. The main source is [G02]. We discuss baby Verma modules for rational Cherednik algebras at t = 0.
متن کاملFinite Dimensional Modules for Rational Cherednik Algebras
We construct and study some finite dimensional modules for rational Cherednik algebras for the groups G(r, p, n) by using intertwining operators and a commutative family of operators introduced by Dunkl and Opdam. The coinvariant ring and an analog of the ring constructed by Gordon in the course of proving Haiman’s conjectures on diagonal coinvariants are special cases. We study a certain hyper...
