Minimal $C^1$-diffeomorphisms of the circle which admit
measurable fundamental domains (JAPANESE)
[ Abstract ]
We construct, for each irrational number $\\alpha$, a minimal
$C^1$-diffeomorphism of the circle with rotation number $\\alpha$
which admits a measurable fundamental domain with respect to
the Lebesgue measure.
This is a joint work with Shigenori Matsumoto (Nihon University).
