There are generalizations of the Perron – Frobenius theory to proper cones, to infinite dimensions and to nonlinear maps; see B.-S. Tam [Taiwanese J. Math. 5, No. 2, 207–277 (2001; Zbl 0990.15009)]. The author considers positively homogeneous and superadditive maps \(\Lambda\), which act continuously on a finite dimensional proper subcone \(\mathbb P\) of a Euclidean space. He investigates the existence of eigenvectors at the boundary of the cone and uses Gateaux derivatives of \(\Lambda\) at the boundary, \(\partial P\), of the cone to detect nonlinearities and to turn them efficiently into estimates of Collatz–Wielandt numbers.
