There, a fixed point corresponds to a spherical residue being stabilized. This has many useful applications, as it can often be used to reduce from a general non-spherical Kac-Moody group (with infinite Weyl group) to a spherical one -- i.e., to an algebraic group, where one can then apply all the usual tools. Very handy! | |
