A characterization of
bounded symmetric domains of type IV by their group of holomorphic
automorphisms |
| Speaker: |
Laura Geatti (Universitá de
Roma 2, Tor Vergata) |
| Location: |
sala 10B |
| |
Abstract: It was proved
by A. Isaev that the unit ball Bˆn in C^n is characterized by its group
of holomorphic automorphisms among Stein manifolds of the same dimension,
i.e. an n-dimensional Stein manifold whose group of holomorphic
automorphisms is isomorphic to Aut(B^n) is necessarily biholomorphic to
B^n. This result was later extended to the n-dimensional polydisk by A.
Kodama and S. Shimizu. We show that an analogous result holds for
bounded symmetric domains of type IV and we discuss possible extensions
to the general case. |

Cohomology of real
Grassmanian manifolds |
| Speaker: |
Luis Casian (Ohio State
University) |
| Location: |
sala 10 B |
| |
Abstract: An explicit and
simple construction of the incidene graph for the integral cohomolog of
real Grassmanniannian is given in terms of the Young diagrams filled
with the letter $q$ in checkered pattern. There are two types of graphs,
one for the trivial coefficients and other for twisted coefficients. An
explicit formula of the Poincaré polynomial is derived for $Gr(k,n)$.
The Poincaré polynomial is also related to the number of points on $Gr(k,n)$
over a finite field $F_q$ with $q$ used in the Young diagrams. This is
also related to integral systems (KP). |
