Lou’s fixed point theorem in a space of continuous mappings. (English) Zbl 1106.47049

The purpose of this paper is twofold. First, the author gives an essentially simplified proof of a fixed point theorem of B.–D.Lou [Proc.Am.Math.Soc.127, No. 8, 2259–2264 (1999; Zbl 0918.47046)]. Second, he shows that the proof of a similar fixed point theorem due to E. de Pascale and L. de Pascale [Proc.Am.Math.Soc.130, No. 11, 3249–3254 (2002; Zbl 1002.47031)] does not require the use of \(K\)-normed spaces.
