Courbure et Polygone de Newton
2000 Mathematics Subject Classification: 26E35, 14H05, 14H20. The object of this article relates to the study of the complex algebraic curves by using the concept of envelope convex. One proposes to characterize the points of a holomorphic complex curve (C) and to associate a metric invariant to them ( generalized curvature), by using the equations of the various segments constituting the polygon of Newton associated with (C).
