Ono, Kaoru

/ School of School of Mathematics


Kaoru Ono's main research interest is symplectic geometry, in particular, Floer theory, the theory of holomorphic curves and their applications.
In a joint work with K. Fukaya, he constructed Gromov-Witten invariants for arbitrary closed symplectic manifolds as well as Floer thoery for periodic Hamiltonian systems, hence obtained the affirmative answer to Betti number version of Arnold's conjecture.
He also proved the flux conjecture, which states that the group of Hamiltonian difffeomorphisms is closed in the identity component of the group of symplectomorphisms with respect to $C^1$-topology for any closed symplectic manifolds. In these years, he has been collaborating with K. Fukaya, Y.-G. Oh and H. Ohta in general study of Floer theory of
Lagrangian submanifolds and its applications.
