The Arnold conjecture and Floer theory Yoshiro YABU 6月2日(金) 13時30分
In the 1960s, Arnold conjectured that for a generic Hamiltonian system on a symplectic manifold $M$, the number of periodic orbits is greater than the sum of the Betti numbers of $M$. Floer [1] proved this conjecture under the assumption that a symplectic manifold is monotone. His proof is based on an infinite-dimensional version of Morse theory with an application of pseudo-holomorphic curves introduced by Gromov [2]. |
