Rassias, George M. Homeomorphisms of the sphere and a generalization of the Whyburn conjecture for compact connected manifolds with boundary. (English) Zbl 0644.57008 Colloq. Math. 52, 199-203 (1987). The author proves some known results (e.g. any auto-homeomorphism of a disc \(D^ n\) being identity on \(\partial D^ n\) is isotopic (mod \(\partial D^ n)\) to identity) and states some new results (e.g. a generalization of the Whyburn conjecture).
