Solution to a semilinear problem on type II regions determined by the Fucik spectrum. <i>Electronic Journal of Differential Equations, 2003</i>(08), pp. 1-10.1072-6691https://hdl.handle.net/10877/12575We prove the existence of solutions to the semi-linear problem u'' (x) + ⍺u+(x) + βu-(x) = ƒ(x), x ∈ (0, π), u(0) = u(π) = 0 where the point (⍺, β) falls in regions of type (II) between curves of the Fučík spectrum. We use a variational method based on the generalization of the Saddle Point Theorem.Text10 pages1 file (.pdf)enAttribution 4.0 InternationalResonanceEigenvalueJumping nonlinearitiesFucik spectrumArticle
