De Rham cohomology of the weak stable foliation of the geodesic flow of a hyperbolic surface
Hirokazu Maruhashi, Mitsunobu Tsutaya
We compute the de Rham cohomology of the weak stable foliation of the geodesic flow of a connected orientable closed hyperbolic surface with various coefficients. For most of the c…

Vanishing of cohomology and parameter rigidity of actions of solvable Lie groups
Hirokazu Maruhashi
We give a sufficient condition for parameter rigidity of actions of solvable Lie groups, by vanishing of (uncountably many) first cohomologies of the orbit foliations. In some case…
