| Research Abstract |
Manifolds are mathematical objects which generalize curves in a plane, surfaces in a space, etc. In modern physics, manifolds are used as a mathematical model of the universe. Over the last two decades, Calabi-Yau manifolds have been attracting attentions of both physicists and mathematicians. In this research, a detailed mathematical study has been done on some geometric invariants, called Gromov-Witten invariants, of Calabi-Yau manifolds. In particular mathematical structures in a certain recursive equation for computing the invariants have been revealed.
