  • Discrete series characters for affine Hecke algebras and their formal degrees (2010)

    Auteurs:Opdam, E.; Solleveld, M.
    In:ACTA MATH-DJURSHOLM, 205(1), 105 - 187. ISSN 00015962.

    Samenvatting:

    We introduce the generic central character of an irreducible discrete series representation of an affine Hecke algebra. Using this invariant we give a new classification of the irreducible discrete series characters for all abstract affine Hecke algebras (except for the types ${E_{n}^{(1)}}$ , n=6,

  • Homological algebra for affine Hecke algebras (2009)

    Auteurs:Opdam, E.; Solleveld, M.
    In:Advances in Mathematics, 220(5), 1549 - 1601. ISSN 00018708.

    Samenvatting:

    In this paper we study homological properties of modules over an affine Hecke algebra H. In particular we prove a comparison result for higher extensions of tempered modules when passing to the Schwartz algebra S, a certain topological completion of the affine Hecke algebra. The proof is self-contai

  • The Schwartz algebra of an affine Hecke algebra (2008)

    Auteurs:Delorme, P.; Opdam, E.M.
    In:Journal für die reine und angewandte Mathematik, 59 - 114. ISSN 00754102.

  • Analysis on the crown domain (2008)

    Auteurs:Krötz, B.; Opdam, E.
    In:Geometric and Functional Analysis, 18(4), 1326 - 1421. ISSN 1016443x.

    Samenvatting:

    This paper is a further development of complex methods in harmonic analysis on semi-simple Lie groups [AG], [BeR], [KrS1,2]. We study the growth behaviour of the holomorphic extension of the orbit map of the spherical vector of an irreducible spherical representation of a real reductive group G when

  • The Central Support of the Plancherel Measure of an Affine Hecke Algebra (2007)

    Auteur:Opdam, E.M.
    In:Moscow Mathematical Journal, 7(4). ISSN 16093321.

    Samenvatting:

    Abstract: We give conceptual proofs of certain basic properties of the arrangement of shifted root hyperplanes associated to a root system R0 and a W0=W(R0)-invariant real valued parameter function on R0. The method is based on the role of this shifted root hyperplane arrangement for the harmonic an

  • Periodic Integrable Systems with Delta-Potentials (2006)

    Auteurs:Emsiz, E.; Opdam, E.M.; Stokman, J.V.
    In:Communications in Mathematical Physics, 264(1), 191 - 225. ISSN 00103616.

    Samenvatting:

    Abstract In this paper we study root system generalizations of the quantum Bose-gas on the circle with pair-wise delta-function interactions. The underlying symmetry structures are shown to be governed by the associated graded algebra of Cherednik's (suitably filtered) degenerate double affine Hecke

  • On the spectral decomposition of affine Hecke algebras (2004)

    Auteur:Opdam, E.M.
    In:J. Inst. Math. Jussieu, 3, 1 - 117. ISSN 14747480.

    Samenvatting:

    Abstract: An affine Hecke algebra H contains a large abelian subalgebra A spanned by the Bernstein-Zelevinski-Lusztig basis elements theta x, where x runs over (an extension of) the root lattice. The centre Z of H is the subalgebra of Weyl group invariant elements in A. The natural trace ('evaluatio

  • On the category O for rational Cherednik algebras (2003)Open access
