Outline of Final Research Achievements

Mirror symmetry is a symmetry which interchanges the role of the symplectic geometry and complex algebraic geometry. The purpose of this reserch is a trial for a deep understanding of the non-commutative Hodge theory in the theorey of the mirror symmetry and for a solution to important problems in related areas.
The following are examples of our research results. Motivated by the non-commutative Hodge theory for categories of matrix factorizations, we proposed a set of axioms for orbifold Jacobian algebras, and we proved the existence and the uniqueness of them. We have also been studying the entropy of endo-functors on derived categories of coherent sheaves on smooth projective varieties and show the Gromov-Yomdin type theorem for some varieties.
