We present a lower bound for a fragmentation norm and construct a bi-Lipschitz embedding [Formula: see text] with respect to the fragmentation norm on the group [Formula: see text] of Hamiltonian diffeomorphisms of a symplectic manifold [Formula: see text]. As an application, we provide an answer to Brandenbursky’s question on fragmentation norms on [Formula: see text], where [Formula: see text] is a closed Riemannian surface of genus [Formula: see text]. - Morimichi Kawasaki, Ryuma OritaCommunications in Contemporary Mathematics 23 (05) 2050047 - 2050047 0219-1997 2020/07/07 [Refereed][Not invited]
In this paper, we introduce the notion of pseudoheaviness of closed subsets of closed symplectic manifolds and prove the existence of pseudoheavy fibers of moment maps. In particular, we generalize Entov and Polterovich’s theorem, which ensures the existence of non-displaceable fibers. As its application, we provide a partial answer to a problem posed by them, which asks the existence of heavy fibers. Moreover, we obtain a family of singular Lagrangian submanifolds in [Formula: see text] with various rigidities. - Morimichi KawasakiJournal of Symplectic Geometry 17 (1) 239 - 249 1527-5256 2019 [Refereed][Not invited]

Hofer’s norm (metric) is an important and interesting topic in symplectic geometry. In the present paper, we define fragmented Hofer’s norms which are Hofer’s norms controlled by fragmentation norms and give some observations on fragmented Hofer’s norms. - Morimichi KawasakiProceedings of the American Mathematical Society, Series B 5 (1) 1 - 5 2018/01/22 [Refereed][Not invited]
Let be or . We conjecture that any semi-homogeneous subset-controlled quasimorphism on can be extended to a homogeneous subset-controlled quasimorphism on and also give a theorem supporting this conjecture by using a Bavard-type duality theorem on conjugation invariant norms.
