On some properties of orientation-preserving surjections on the circle
On iterative roots of a homeomorphism of the circle with an irrational rotation number.
Some remarks on the general theorem of the existence of iterative roots of homeomorphisms with a rational rotation number
We show that the theorem proved in [8] generalises the previous results concerning orientation-preserving iterative roots of homeomorphisms of the circle with a rational rotation number (see [2], [6], [10] and [7]).
