Streszczenie
The non-local Gel'fand problem, $\Delta v + \lambda e^v/\! \int_{\Omega}e^vdx= 0$ with Dirichlet boundary condition, is studied on an $n$-dimensional bounded domain $\Omega$. If it is star-shaped, then we have an upper bound of $\lambda$ for the existence of the solution. We also have infinitely many bendings in $\lambda$ of the connected component of the solution set in $\lambda, v$ if $\Omega$ is a ball and $3\leq n\leq 9$.
