Harmonic measures and rigidity for transverse foliations on Seifert -manifolds
Masanori Adachi, Yoshifumi Matsuda, Hiraku Nozawa
Thurston proposed, in part of an unfinished manuscript, to study surface group actions on by using an -connection on the suspension bundle obtained from a harmonic measu…
Relative simplicity of the universal coverings of transformation groups and Tsuboi's metric
Morimichi Kawasaki, Mitsuaki Kimura, Hiroki Kodama +3
Many transformation groups on manifolds are simple, but their universal coverings are not. In the present paper, we study the concept of relatively simple group, that is, a group w…
Harmonic measures and rigidity for surface group actions on the circle
Masanori Adachi, Yoshifumi Matsuda, Hiraku Nozawa
We study rigidity properties of actions of a torsion-free lattice of on the circle . We follow the approaches of Frankel and Thurston proposed in pre…
Invariable generation of certain groups of piecewise linear homeomorphisms of the interval
Yoshifumi Matsuda, Shigenori Matsumoto
We show that certain groups of piecewise linear homeomorphims of the interval are invariably generated.
Rotation number and lifts of a Fuchsian action of the modular group on the circle
Yoshifumi Matsuda
We characterize the semi-conjugacy class of a Fuchsian action of the modular group on the circle in terms of rotation numbers of two standard generators and that of their product.…
On relative hyperbolicity for a group and relative quasiconvexity for a subgroup
Yoshifumi Matsuda, Shin-ichi Oguni, Saeko Yamagata
We consider two families of subgroups of a group. Each subgroup which belongs to one family is contained in some subgroup which belongs to the other family. We then discuss relatio…
