T. Ekholm: Contact homology of Legendrian submanifolds of standard 
           contact R^{2n+1}.

We define contact homology of Legendrian submanifolds in R^{2n+1} and use it
to give new examples and new constructions of Legendrian knotted submanifolds.

H.J. Geiges: Contact topology of torus bundles

This talk discusses various aspects of the contact topology of torus bundles,
such as questions of symplectic fillability and homotopy information about the
space of contact structures.

S. Strle:  Homology lens spaces and four-ball 

I will discuss an application of Heegaard Floer homology to four-ball genus of
links. The idea is to encode the information about the slice surface in a
4-manifold X, and the information about the link in its boundary Y. Using the
correction term (which is analogous to Froyshov invariant in Seiberg-Witten
theory) one can find obstructions to Y bounding X.  This is joint work with
Brendan Owens.

D.T. Martinez:  Ample bundles for odd dimensional manifolds

We show how certain geometric structures on odd dimensional manifolds $M$
(analogs of symplectic structures with include contact structures, cosympletic
structures, smooth taut foliations,...) give rise to ample bundles
$L\rightarrow M$, out of which we produce differential topologic constructions
compatible with the geometric structure.

C. Manolescu: Gauge theory and stable homotopy

We survey recent work on an algebraic-topologic approach to Seiberg-Witten
theory in three and four dimensions. In dimension 4, there is a stable
homotopy version of the Seiberg-Witten invariant, due to Bauer and Furuta.
The basic idea is to approximate infinite-dimensional configuration spaces
by finite-dimensional ones. Doing the same thing in dimension 3, one can
construct a spectrum whose homology is the Floer homology, as well as
define relative invariants of four-manifolds with boundary. The end result
is expected to be a "spectra-valued topological quantum field theory."

A. Teleman: Applications of gauge theory in complex geometry

We present several interesting applications of Gauge Theory in Complex
Geometry. First, we will present a short proof of Bogomolov's theorem on class
VII surfaces with $b_2=0$, which uses Donaldson theory.  Second, we will
explain how Donaldson Theory and the Witten conjecture can be used to solve
the existence problems for holomorphic structures on vector bundles over
non-algebraic surfaces.  Third, we describe the "gauge theoretical'
Gromov-Witten invariants of the Grassmann manifold, and show how these
invariants can be used to solve an enumerative problem in Algebraic Geometry.

M. Abreu: Topological decomposition of a symplectomorphism group


Let M denote the manifold S^2 x S^2 equipped with a symplectic form having 
ratio of the area of the two spheres in the interval (1,2]. In this talk I 
will describe recent work of S.Anjos and G.Granja, expressing the 
symplectomorphism group of M as the pushout (or amalgam) of some of its 
compact Lie subgroups. This result suggests an appropriate framework to 
derive and interpret previous results regarding the topology of certain 
symplectomorphism groups.

P. Ghiggini: Classification of tight contact structures on some Seifert manifolds

We give a complete isotopy classification of tight contact structures
on Seifert manifolds over $T^2$ with one singular fibre.
