| Research Abstract |
For any symplectic polynomial endomorphism of an affine space, the representative defined a sheaf on the affine space. Its triviality is equivalent to the existence of a lift of the map to an Endomorphism of a Weyl algebra. Next we have used the theory of Abe-Yoshinaga on a behavior of reflexive sheaves on the hyperplane at infinity and obtained a result which says that the absence of the singularity on the infinity implies an existence of a` quantization' of a symplectic endomorphism of an affine space. This gives an evidence of effectiveness of ordinary commutative algebraic geometry of' compact' spaces such as projective spaces in dealing with non commutative objects.
