Nonlinear Spectrum and Fixed Point Index for a Class of Decomposable Operators
We study a class of nonlinear operators that can be written as the composition of a linear operator and a nonlinear map. We obtain results on fixed point index based on parameters that are related to the definitions of nonlinear spectra. As a particular case, existence of positive solutions for a se...
