Extensions between Simple Modules for Frobenius Kernels
Introduction Let G be a simply connected and connected semisimple group over an algebraically closed field k of characteristic p > 0. T ⊂ G is a maximal torus and R is the root system relative to T . X(T ) is the weight lattice. Let B ⊃ T be a Borel subgroup corresponding to the negative roots R− = R. Denote by Gr the r-th Frobenius kernel of G. The socle and radical structures of the cohomolog...
متن کاملType A molecules are Kazhdan-Lusztig
Let (W,S) be a Coxeter system. A W -graph is an encoding of a representation of the corresponding Iwahori-Hecke algebra. Especially important examples include the W -graph corresponding to the action of the Iwahori-Hecke algebra on the Kazhdan-Lusztig basis as well as this graph’s strongly connected components (cells). In 2008, Stembridge identified some common features of the Kazhdan-Lusztig g...
متن کاملQuotient Curves of the Deligne-lusztig Curve of Suzuki Type
Inspired by a recent paper of Garcia, Stichtenoth and Xing [2000, Compositio Math. 120, 137–170], we investigate the quotient curves of the Deligne-Lusztig curve associated to the Suzuki group Sz(q).
متن کاملRank and Conjugation for the Frobenius Representation of an Overpartition
We discuss conjugation and Dyson’s rank for overpartitions from the perspective of the Frobenius representation. More specifically, we translate the classical definition of Dyson’s rank to the Frobenius representation of an overpartition and define a new kind of conjugation in terms of this representation. We then use q-series identities to study overpartitions that are self-conjugate with resp...
متن کامل“Frobenius twists” in the representation theory of the symmetric group
For the general linear group GLn(k) over an algebraically closed field k of characteristic p, there are two types of “twisting” operations that arise naturally on partitions. These are of the form λ → pλ and λ → λ+ prτ The first comes from the Frobenius twist, and the second arises in various tensor product situations, often from tensoring with the Steinberg module. This paper surveys and adds ...
