About amenability of subgroups of the group of diffeomorphisms of the interval

A series of averaging functionals on the space of continuous functions on the group of diffeomorphisms of the interval is found.

Amenability of several discrete subgroups of the group of diffeomorphisms Diff3([0,1]) of the interval is proved. In particular, a way is given of solving the problem of amenability of Thompson's group F.
