A variational approach to nonresonance with respect to the Fučik spectrum

Nonlinear Analysis: Theory, Methods & Applications, 1992
The paper is concerned with the periodic problem (1) \(-u''(t) = f(t,u(t))\) in \([0,2\pi]\), \(u(0) = u(2 \pi)\), \(u'(0) = u'(2\pi)\). The authors give sufficient conditions for the existence of at least one solution \(u\) of (1) in \(H^ 2(0,2\pi)\). The nonlinearity \(f(t,s)\) interferes in a certain sense with the associated Fučík spectrum.

The functional Fučik spectrum has empty interior

Proceedings of the Royal Society of Edinburgh: Section A Mathematics, 2003
We define a functional version of the Fučik spectrum for the Laplacian and we prove that this functional spectrum has empty interior.

Nonresonance with respect to the Fuc̆ik spectrum for periodic solutions of second order ordinary differential equations

Nonlinear Analysis: Theory, Methods & Applications, 1990
This paper is concerned with the existence of periodic solutions for the equation \(x''(t)+g(t,x(t))=e(t)\) in the case where the nonlinearity g(t,s) lies asymptotically between 0 and one point \((Q_+,Q_ -)\) of the first branch of the Fučik spectrum, or between two points \((q_+,q_ -)\) and \((Q_+,Q_ -)\) of two consecutive branches of that spectrum ...
