學(xué)術(shù)活動(dòng)主題:Closed Orbits in Nonlinear Hamiltonian Systems
內(nèi)容簡(jiǎn)介:
In this talk, we consider the problems of existence and stability of closed characteristics on compact convex hypersurfaces in $\R^{2n}$. Especially, we show the existence of at least three geometrically distinct closed characteristics on every compact convex hypersurfaces in $\R^{6}$, which gives a confirmed answer in the case $n=3$ to a long standing conjecture in Hamiltonian analysis 主持(講)人 王嵬博士(北京大學(xué))
