YET ANOTHER SPECTRUM FOR NONLINEAR OPERATORS IN BANACH SPACES
Jürgen Appell, Alessandro Calamai, Andreas Schmied · Università Politecnica delle Marche (Università Politecnica delle Marche) · 2013
In this paper we study a nonlinear spectrum which is related to a similar spectrum introduced recently by Furi, Vignoli, and the second author. We compare this spectrum with other nonlinear spectra, study its analytical and topological properties, and briefly indicate a possible application.
