A note on the example of J. Andres concerning the application of the Nielsen fixed-point theory to differential systems. (English) Zbl 1040.34022

Summary: The goal of this note is two-fold: to give a slight improvement of the example due to J. Andres in [Proc. AMS 128, 2921–2931 (2000; Zbl 0964.34030)] concerning the application of the Nielsen number to differential equations, and a reprovement of the method, allowing us to avoid one condition (the connectedness of ANR-spaces).
