Relative tangent cone of analytic sets

Danuta Ciesielska (2012)

Annales Polonici Mathematici

Similarity:

We give a characterization of the relative tangent cone of an analytic curve and an analytic set with an improper isolated intersection. Moreover, we present an effective computation of the intersection multiplicity of a curve and a set with s-metrization.

Deformations of coherent foliations on a compact normal space

Geneviève Pourcin (1987)

Annales de l'institut Fourier

Similarity:

An universal analytic structure is construted on the set of (singular) holomorphic foliations on a normal compact space. Such a foliation is by definition a coherent subsheaf of the holomorphic tangent sheaf stable by the Lie-bracket
