Multiple bifurcations of sign-changing solutions for one-dimensional $p$-Laplace equation with a critical weight

Abstract

In this paper, we study one-dimensional $p$-Laplace equation, whose weight function has a critical power at the origin. We show the existence of infinitely many bifurcation branches emanating from the same single point and also study the existence and multiplicity of sign-changing solutions. Moreover, we investigate the global shape of bifurcation branches.
