This thesis studies the geometry of the specialization space φ : (X, 0) → (C, 0) of a germ of complex analytic singularity (X, 0) to its tangent cone (CX,0 , 0) from the point of view of Whitney equisingularity . The application φ gives us a flat family of germs with a section such that for t different from 0 the germ φ−1 (t) is isomorphic to (X, 0) and the special fibre is isomorphic to the tangent cone. The objective is to establish conditions on the strata of the minimal Whitney stratification of (X, 0) that will ensure the equisingularity between the germ and its tangent cone, thus generalizing the result of Lê and Teissier for hypersurfaces of C3 which prouves that the absence of exceptional tangents is sufficient. In this work we prou...
