Parametrized singularly perturbed boundary value problems
Boundary value problems for some \((\varepsilon,\lambda)\)-families of singularly perturbed higher order ordinary differential equations are considered. The author applies an approach of his paper [J. Differ. Equation 106, 312-331 (1993)] to give the lower estimates for the number of parameters \(\lambda\in \mathbb{R}^ m\) for which those equations possess a solution.
