Global bifurcation and nodal solutions for homogeneous Kirchhoff type equations
Electronic Journal of Qualitative Theory of Differential Equations, 2020 In this paper, we shall study unilateral global bifurcation phenomenon for the following homogeneous Kirchhoff type problem \begin{equation*} \begin{cases} -\left(\int_0^1 \left\vert u'\right\vert^2\,dx\right)u''=\lambda u^3+h(x,u,\lambda)&\text{in}\,\, (

Nodal Accuracy Improvement Technique for Linear Elements with Application to Adaptivity
Applied Sciences, 2023 In the finite element method, the conventional linear elements have long been precluded, due to their low accuracy of nodal displacements, from the analysis of super-convergence and adaptivity via the element energy projection (EEP) technique.
