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

Published 11 Apr 2021 in math.SG | (2104.05098v1)

Abstract: 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.
