关于余切丛中Lagrange弗洛尔同调的部分拟态射和乘积的注记

A note on partial quasi-morphisms and products in Lagrangian Floer homology in cotangent bundles

Jelena Katić, Darko Milinković, Jovana Nikolić

摘要:

利用余法边界条件下拉格朗日弗洛尔同调的谱不变量,在余切丛的Hamilton同同态群上定义了部分拟态射,其中缺少与PSS同构相容的积和同调交积.

英文摘要:

We define partial quasi-morphisms on the group of Hamiltonian diffeomorphisms of the cotangent bundle using the spectral invariants in Lagrangian Floer homology with conormal boundary conditions, where the product compatible with the PSS isomorphism and the homological intersection product is lacking.
