Groups of Cr,s-diffeomorphisms related to a foliation
Jacek Lech1, Tomasz Rybicki2
Banach Center Publ. 76 (2007), 437-450
Abstract: 
The notion of a $C^{r,s}$-diffeomorphism related to a
foliation is introduced. A perfectness theorem for the group of
$C^{r,s}$-diffeomorphisms is proved. A remark on
$C^{n+1}$-diffeomorphisms is given.
