Numerical verification method for solutions of the perturbed Gelfand equation

A numerical veri cation method for radially symmetric solutions of the perturbed Gelfand equation is presented for the case in which this equation possesses turning points. We use Nakao's method with local uniqueness to enclose the continua of solutions and a bordering algorithm in order to treat a turning point. We describe veri cation procedures in detail and give a numerical example.
