Abstract

Abstract: The Iwahori–Hecke algebra H(G, B) of a finite Chevalley group G with respect to a Borel subgroup B is described as a deformation of the group algebra of the Weyl group of G Similarly, the +-part of the quantized enveloping algebra $${{U^+_v (\mathfrak{g})}}$$ associated with a semisimple Lie algebra $${{\mathfrak{g}}}$$ can be viewed as a deformation of the +-part of the universal enveloping algebra $${{U(\mathfrak{g})}}$$ . In both cases it is shown how information concerning the deformed algebras H(G, B) and $${{U^+_v (\mathfrak{g})}}$$ can be used to obtain results about the representation theory of the Chevalley group G and the semisimple Lie algebra $${{\mathfrak{g}}}$$ .

<abstract lang="en">Abstract: The Iwahori–Hecke algebra H(G, B) of a finite Chevalley group G with respect to a Borel subgroup B is described as a deformation of the group algebra of the Weyl group of G Similarly, the +-part of the quantized enveloping algebra $${{U^+_v (\mathfrak{g})}}$$ associated with a semisimple Lie algebra $${{\mathfrak{g}}}$$ can be viewed as a deformation of the +-part of the universal enveloping algebra $${{U(\mathfrak{g})}}$$ . In both cases it is shown how information concerning the deformed algebras H(G, B) and $${{U^+_v (\mathfrak{g})}}$$ can be used to obtain results about the representation theory of the Chevalley group G and the semisimple Lie algebra $${{\mathfrak{g}}}$$ .</abstract>
