We show that a Berezin-type quantization can be achieved on a compact even dimensional manifold M2d by removing a skeleton M0 of lower dimension such that what remains is diffeomorphic to R2d which we identify with Cd and embed in CPd . A local Poisson structure and Berezin-type quantization are induced from CPd . This construction depends on the diffeomorphism. However, suppose X=M∖M0 has a complex structure and we have from X∖X0 , (X 0 a set of measure zero or empty) a biholomorphism from it to Cd∖N0 , (where N0 is of measure zero or empty). As before we embed Cd∖N0 in Cdandtheninto{\mathbb C}P^ dandwehaveaBerezin−typequantizationinducedfrom{\mathbb C}P^ d.Ifweuseanotherbiholomorphism,wehaveamapofthetwoHilbertspacesunderconsiderationsuchthatthereproducingkernelofonemapstothereproducingkerneloftheotherandwehaveanequivalentquantization.Wehaveasimilarconstructionwhereweconsideranarbitrarycomplexmanifoldanduselocalcoordinatestoinducethequantizationfrom{\mathbb C}P^ d$ . We study the possibility of deï¬ning a global Berezin quantization on compact complex manifolds. Finally we give a simple construction of pullback coherent states on compact smooth manifolds. | |
