Using a modified method of boundary-layer functions, we construct a complete uniform asymptotic solution to the singularly perturbed Cauchy problem for a second-order linear inhomogeneous ordinary differential equation with a multiple turning point on the real axis.
Keywords: asymptotics, boundary-layer function, Cauchy problem, bisingular problem, turning point, generalized method of boundary-layer functions, singular perturbation.
