    Abstract

    We prove a version of the Gindikin-Karpelevich formula for untwisted affine
    Kac-Moody groups over a local field of positive characteristic.

  2. Pursuing the double affine Grassmannian II: Convolution.

    Authors: Alexander Braverman, Michael Finkelberg
    Subjects: Algebraic Geometry
    Abstract

    This is the second paper of a series (started by arXiv:0711.2083) which
    describes a conjectural analog of the affine Grassmannian for affine Kac-Moody
    groups (also known as the double affine Grassmannian). The current paper is
    dedicated to describing a conjectural analog of the convolution diagram for the
    double affine Grassmannian. In the case when G=SL(n) our conjectures can be
    derived from arXiv:0809.2605.
