  1. On elliptic Calogero-Moser systems for complex crystallographic reflection groups.

    Abstract

    To every irreducible finite crystallographic reflection group (i.e., an
    irreducible finite reflection group G acting faithfully on an abelian variety
    X), we attach a family of classical and quantum integrable systems on X (with
    meromorphic coefficients). These families are parametrized by G-invariant
    functions of pairs (T,s), where T is a hypertorus in X (of codimension 1), and
    s in G is a reflection acting trivially on T. If G is a real reflection group,
    these families reduce to the known generalizations of elliptic Calogero-Moser
    systems, but in the non-real case they appear to be new.

  2. Lecture notes on Cherednik algebras.

    Authors: Xiaoguang Ma, Pavel Etingof
    Subjects: Representation Theory
    Abstract

    The present notes are based on a course on Cherednik algebras given by the
    first author at MIT in the Fall of 2009. Their goal is to give an introduction
    to Cherednik algebras, and to review the web of connections between them and
    other mathematical objects.

  3. Quantum symmetric pairs and representations of double affine Hecke algebras of type $(C^\vee_n,C_n)$.

    Authors: David Jordan, Xiaoguang Ma
    Subjects: Quantum Algebra
    Abstract

    We build representations of the affine and double affine braid groups and
    Hecke algebras of type $(C^\vee_n,C_n)$, based upon the theory of quantum
    symmetric pairs $(U,B)$. In the case $U=U_q(gl_N)$, our constructions provide a
    quantization of the representations constructed by Etingof, Freund and Ma in
    arXiv:0801.1530, and also a type $BC$ generalization of the results in
    arXiv:0805.2766.
