A fold bifurcation theorem of degenerate solutions in a perturbed nonlinear equation
Consider a nonlinear equation \(F(\varepsilon,\lambda,u)=0\), where \(\varepsilon\) is a perturbation parameter, \(\lambda\) is a real number, \(u\) belongs to a Banach space, and \(F\) is a differentiable mapping into a Banach space. The authors use the generalized saddle-node bifurcation theorem to obtain a general bifurcation result.
