The Brouwer degree associated to classical eigenvalue problems and applications to nonlinear spectral theory
Pierluigi Benevieri, Alessandro Calamai, Massimo Furi +1
Thanks to a connection between two completely different topics, the classical eigenvalue problem in a finite dimensional real vector space and the Brouwer degree for maps between o…
