摘要：

We consider singularly perturbed analytic differential equations in the complex domain with a turning point of order p and a p-dimensional control parameter a. We prove existence and exponential closeness of well behaved solutions under some geometric and transversality conditions. Furthermore, properties of formal solutions are studied and an application to "least term summation" is given. (C) Academie des Sciences/Elsevier, Paris.
