Abstract Double boundary layers of quadratic nonlinear singularly perturbed boundary value problem with infinite boundary values is studied. Using the boundary layer correction function, its asymptotic solution is constructed, and using the theory of differential inequality, the uniformly valid asymptotic estimation is presented. Finally, an example is given to verify the validity of the relevant conclusions.
