Outline of Final Research Achievements

We consider the algebra obtained by convergent star products. We study star exponentials defined in the algebra which are noncommutative or commutative. We have shown star exponentials of quadratic polynomials have singularities and we obtain several identities in the star product algebras using the singularities.
We also consider applications of star product algebras to geometry and mathematical physics. In star product algebras, transformation of expression is naturally introduced and then one has a flat connection. It is shown that the parallel transport in geometric quantization theory is equivalent to that of star product algebras with respect to the flat connection. We also obtain a geometric point of view of eigenvalue problem for operators via star product algebras and the Maslov quantization condition, and we consider a concrete model to which we can apply noncommutative geometry by star products.
