摘要
We describe a numerical method with guaranteed accuracy to enclose a double turning point for a radially symmetric solution of the perturbed Gelfand equation. We use Nakao's method and a system of equations defined on an extended space to enclose a double turning point. We describe verification procedures in detail and give a numerical example.
