Stratifying endomorphism algebras using exact categories
Autor: Jie Du, Leonard L. Scott, Brian Parshall
Publikováno v: Journal of Algebra. 475:229-250
This paper constructs enlargements of Hecke algebras over Z [ t , t − 1 ] to certain standardly stratified algebras. The latter are obtained as endomorphism algebras of modules with dual left cell module filtrations in the sense of Kazhdan–Luszti

Some Tables of Right Set Properties in Affine Weyl Groups of Type A
Autor: Ethan C. Zell, Leonard L. Scott
Publikováno v: Springer Proceedings in Mathematics & Statistics ISBN: 9783030115203
The tables of the title are a first attempt to understand empirically the sizes of certain distinguished sets, introduced by Hankyung Ko, of elements in affine Weyl groups. The distinguished sets themselves each have a largest element w, and all othe

Computing individual Kazhdan–Lusztig basis elements
Autor: Timothy Sprowl, Leonard L. Scott
Publikováno v: Journal of Symbolic Computation. 73:244-249
In well-known work, Kazhdan and Lusztig (1979) defined a new set of Hecke algebra basis elements (actually two such sets) associated to elements in any Coxeter group. Often these basis elements are computed by a standard recursive algorithm which, fo

Local and global methods in representations of Hecke algebras
Autor: Brian Parshall, Leonard L. Scott, Jie Du
This paper aims at developing a "local--global" approach for various types of finite dimensional algebras, especially those related to Hecke algebras. The eventual intention is to apply the methods and applications developed here to the cross-charact

Bounding Cohomology for Finite Groups and Frobenius Kernels
Autor: Daniel K. Nakano, Brian Parshall, Leonard L. Scott, Cornelius Pillen, David I. Stewart, Christopher P. Bendel
Publikováno v: Algebras and Representation Theory. 18:739-760
Let G be a simple, simply connected algebraic group defined over an algebraically closed field k of positive characteristic p. Let σ :G → G be a strict endomorphism (i.e., the subgroup G(σ) of σ-fixed points is finite). Also, let Gσ be the sche
