Título: Spaces and moduli spaces of Riemannian metrics

Resumen:
The existence and construction of complete metrics with certain 
prescribed curvature properties
such as, e.g., positivity of scalar or Ricci curvature, nonnegativity or

negativity of sectional curvature, etc.,
constitutes a basic question and task in Riemannian geometry.
On the other hand, once the respective existence problem has been
solved,
there is an equally important second one, namely: How `many' metrics of
the
given type are there, and
how `many' different geometries of this kind does the manifold actually 
allow?

To answer these questions, one is led to study the corresponding
spaces of metrics that satisfy the curvature characteristics one is 
interested in,
as well as their respective moduli spaces, i.e., the quotients of these 
spaces
by the action of the diffeomorphism group given by pulling back metrics.

In my talk, I will present and survey recent results about such spaces 
and moduli spaces
of complete Riemannian metrics with curvature bounds on open and closed 
manifolds,
here focussing mainly on connectedness and disconnectedness properties,
and also discuss several open problems and questions in the field.

Están invitados a participar!
