Abstract

We consider a locally path-connected compact metric space KK with finite first Betti number b1(K)b_1(K) and a flow (K,G)(K, G) on KK such that GG is abelian and all GG-invariant functions fC(K)f\in\mathrm{C}(K) are constant. We prove that every equicontinuous factor of the flow (K,G)(K, G) is isomorphic to a flow on a compact abelian Lie group of dimension less than b1(K)b_1(K). For this purpose, we use and provide a new proof for [HJop, Theorem 2.12] which states that for a flow on a locally connected compact space the quotient map onto the maximal equicontinuous factor is monotone, i.e., has connected fibers. Our alternative proof is a simple consequence of a new characterization of the monotonicity of a quotient map p ⁣:KLp\colon K\to L between locally connected compact spaces KK and LL that we obtain by characterizing the local connectedness of KK in terms of the Banach lattice C(K)\mathrm{C}(K).
