Figure 1From: Spectral analysis of the integral operator arising from the beam deflection problem on elastic foundation II: eigenvalues Graph of \(\pmb{\hat{h}(\kappa)}\) . The solid curve represents \(\hat{h}(\kappa)\) which decreases on \([0,\infty)\) approaching \(-2\pi\). The dashed curves represent the function \(\arctan \{ \frac{2\sqrt{2} \kappa ( \kappa^{2} - 1 )}{ \kappa^{4} - 4 \kappa^{2} + 1} \}\).Back to article page
