A variational property on the evolutionary bifurcation curves for the one-dimensional perturbed Gelfand problem from combustion theory

摘要

We study a variational property on the evolutionary bifurcation curves for the one-dimensional perturbed Gelfand problem from combustion theory egin{equation*} egin{cases} u^{prime prime }(x)+lambda exp left( rac{au}{a+u}ight) =0, & -10$ is the activation energy parameter, and $u$ is the dimensionless temperature.
