The Set of Maps F_(ɑ,b): x, ⟼ x + ɑ + b/2π sin(2πx) with any Given Rotation Interval is Contractible

Abstract

Consider the two-parameter family of real analytic maps F_(ɑ,b):x↦x+ɑ+b/2π sin(2πx) which are lifts of degree one endomorphisms of the circle. The purpose of this paper is to provide a proof that for any closed interval I, the set of maps F_(ɑ,b) whose rotation interval is I, form a contractible set.
