Abstract

Building on Donaldson's work on constant scalar curvature metrics, we study the space of regular Kaehler metrics {\cal E}_{\omega}, i.e. those for which deformation quantization has been defined by Cahen, Gutt and Rawnsley. After giving, in Section 2 and 3 a review of Donaldson's moment map approach, we study the ''essential'' uniqueness of balanced basis (i.e. of coherent states) in a more general setting (Theorem \ref{mainteor}). We then study the space {\cal E}_{\omega} and we show how all the tools needed can be defined also in the case of non-compact manifolds.
