2)  Date:  Thursday April 28, 2005,

    Speaker: Jean-Francois Lafont (Binghamton)

    Title: Simplicial norm of non-positively curved locally symmetric spaces.

    Place: Library North 2205 followed by coffee/tea in the Anderson
           Reading Room.

    Abstract:  We will show that the simplicial norms of compact,
    non-positively curved, locally symmetric spaces are always greater
    than 0. This answers a 1982 conjecture of Gromov. Various algebraic,
    geometric, and topological consequences will be discussed. This
    result is joint work with Ben Schmidt.
