| Research Abstract |
The purpose of our study is, to reveal symmetries and structures which are ingeniously hidden in seemingly complicated geometric objects. We mainly developed two devises: One is the degeneration of manifolds, which decomposes complex objects into simpler parts, and the other is the mirror symmetry, which is a kind of duality transformation between geometric objects. As a result, we could define several invariants of manifolds, and calculate them.
