Determining a Connected Split Reductive Group from Its Irreducible Representations
نویسنده
چکیده
We show that a connected split reductive group G over a field of characteristic 0 is uniquely determined up to isomorphism by specifying a maximal torus T of G , the set of isomorphism classes of irreducible representations of G , and the character homomorphism from the Grothendieck ring of G to that of T .

Twelve Bridges from a Reductive Group to Its Langlands Dual
Introduction. These notes are based on a series of lectures given by the author at the Central China Normal University in Wuhan (July 2007). The aim of the lectures was to provide an introduction to the Langlands philosophy. According to a theorem of Chevalley, connected reductive split algebraic groups over a fixed field A are in bijection with certain combinatorial objects called root systems...
متن کاملRemarks on Springer’s Representations
We give an explicit description of a set of irreducible representations of a Weyl group which parametrizes the nilpotent orbits in the Lie algebra of a connected reductive group in arbitrary characteristic. We also answer a question of Serre concerning the conjugacy class of a power of a unipotent element in a connected reductive group.

Let F be a finite extension of Qp. Using the mod p Satake transform, we define what it means for an irreducible admissible smooth representation of an F -split p-adic reductive group over Fp to be supersingular. We then give the classification of irreducible admissible smooth GLn(F )-representations over Fp in terms of supersingular representations. As a consequence we deduce that supersingular...
متن کاملIntersection Cohomology Methods in Representation Theory*
In recent years, the theory of group representations has greatly benefited from a new approach provided by the topology of singular spaces, namely intersection cohomology (IC ) theory. Let G be a connected reductive algebraic group over an algebraically closed field (which will be assumed to be C unless otherwise specified) ; although G itself is clearly a non-singular variety, the study of the...
متن کاملLanglands’ classification of representations of real tori
SupposeG to be a quasi-split reductive group defined over F . To it is associated a connected complex group G∨ whose root datum is dual to that ofG, and the structure ofG determines an algebraic action ofG(F/F ) on G∨. Define G to be the semidirect productG∨⋊WF . Langlands has conjectured a partition of a large part of the set of irreducible representations ofG(F ) into finite packets (calledL ...
