Abstract

In this paper, we investigate the existence of an $S$-shaped connected component in the set of positive solutions of the Dirichlet problem of the one-dimension Minkowski-curvature equation $$ \left\{ \begin{align*}&\Big(\frac{u'}{\sqrt{1-u'^2}}\Big)'+\lambda a(x)f(u)=0,\ \ \ x\in(0,1),\\ &u(0)=u(1)=0,\\\end{align*} \right.$$ where $\lambda$ is a positive parameter, $f\in C[0,\infty)$, $a\in C[0,1]$. The proofs of main results are based upon the bifurcation techniques.

Keywords: $S$-shaped connected component, positive solutions, mean curvature operator, Minkowski space, bifurcation
