In this paper, we consider spaces
M of Riemannian metrics on a closed manifold
M. In the case where the manifold
M is equipped with a symplectic or contact structure, we consider spaces
AM of associated metrics. We study geometric and topological properties of these spaces and Riemannian functionals on spaces
of metrics.
