摘要	In this work, we study the Fucik spectrum for the Schrodinger operator -delta + V when -delta + V is strongly indefinite. More precisely, we aim to show the existence of two Fucik spectrum curves stemming from a distinct eigenvalue, which is in a gap of the essential spectrum. Our method is variational and main difficulties arise from the indefiniteness of the associate functional. We use new strategies to deal with the underlying difficulties of establishing boundedness and compactness properties of (PS) sequences and then use a finite-dimensional approximation method. As an application, we show the existence of a nontrivial solution for nonlinear Schrodinger equations with jumping nonlinearities in strongly indefinite cases.
