Quantization of Kähler manifolds I: geometric interpretation of Berezin's quantization
TL;DR: In this paper, a geometric interpretation of Berezin's symbolic calculus on Kahler manifolds is given, where covariant symbols are defined in terms of coherent states and a function ϴ on the manifold which is the central object of the theory is studied.
Journal ArticleDOI
Equivalence of star products
TL;DR: In this paper, it was shown that equivalence classes of smooth or differentiable star products on a symplectic manifold M are parametrized by sequences of elements in the second de Rham cohomology space of the manifold.
Journal ArticleDOI
Quantization of Kähler manifolds II
TL;DR: In this article, the authors use Berezin's dequantization procedure to define a formal *-product on a dense subalgebra of the algebra of smooth functions on a compact homogeneous Kahler manifold.
Journal ArticleDOI
Lorentz manifolds modelled on a Lorentz symmetric space
TL;DR: In this paper, the authors give examples of Lorentz manifolds modelled on an indecomposable Lévy symmetric space which are geodesically complete and not locally homogeneous.
