Isolated hypersurface singularities, spectral invariants, and quantum cohomology
Yusuke Kawamoto
We study the relation between isolated hypersurface singularities (e.g. ADE) and the quantum cohomology ring by using spectral invariants, which are symplectic invariants coming fr…
Hofer geometry via toric degeneration
Yusuke Kawamoto
The main theme of this paper is to use toric degeneration to produce distinct homogeneous quasimorphisms on the group of Hamiltonian diffeomorphisms. We focus on the (complex -d…
Homogeneous quasimorphisms, -topology and Lagrangian intersection
Yusuke Kawamoto
We construct an example of a non-trivial homogeneous quasimorphism on the group of Hamiltonian diffeomorphisms of the two and four dimensional quadric hypersurfaces which is contin…
On -continuity of the spectral norm for symplectically non-aspherical manifolds
Yusuke Kawamoto
The purpose of this paper is to study the relation between the -topology and the topology induced by the spectral norm on the group of Hamiltonian diffeomorphisms of a closed…
Higher homotopy commutativity and cohomology of finite H-spaces
Yutaka Hemmi, Yusuke Kawamoto
We study connected mod p finite A_p-spaces admitting AC_n-space structures with n<p for an odd prime p. Our result shows that if n is greator than (p-1)/2, then the mod p Steenrod…
