Real analytic lift of foliations of Thurston and Tsuboi

Teruaki Kitano, Yoshihiko Mitsumatsu, Shigeyuki Morita

Thurston constructed codimension one foliations on $S^{3}$ thereby proved that the homomorphism $g v : I ¨ _{3} (B I^_{1}^{\infty}) \to R$ induced by the Godbillon-Vey i…

Lefschetz fibrations on the Milnor fibers of cusp and simple elliptic singularities

Naohiko Kasuya, Hiroki Kodama, Yoshihiko Mitsumatsu +1

We show that the total space of the Milnor fibration associated with any cusp or simple elliptic singularity in complex three variables admits an $S^{1}$ -parametric genus-one Lefsche…

There exist no contact Anosov diffeomorphisms

Masayuki Asaoka, Yoshihiko Mitsumatsu

For any Anosov diffeomorphims on a closed odd dimensional manifold, there exists no invariant contact structure.

On the existence of critical compatible metrics on contact $3$ -manifolds

Yoshihiko Mitsumatsu, Daniel Peralta-Salas, Radu Slobodeanu

We disprove the generalized Chern-Hamilton conjecture on the existence of critical compatible metrics on contact $3$ -manifolds. More precisely, we show that a contact $3$ -manifold…
