Etude des (n+1)-tissus de courbes en dimension n
Dufour Jean-Paul, Daniel Lehmann
For -webs by curves in an ambiant -dimensional manifold, we first define a generalization of the well known Blaschke curvature of the dimension two, which vanishes iff th…
Le rang des tissus de Nakai
Jean Paul Dufour, Daniel Lehmann
According to Alain Hénaut, a planar 4-web is called Nakai's web if the cross-ratio of the tangents to the four foliations at each point is constant and if it has no hexagonal 3-sub…
Courbes ordinaires de genre maximal
Youssef Hantout, Daniel Lehmann
The ordinary algebraic curves of maximal rank are also the arithmetically Cohen-Maccaulay curves of minimal rank. We give sufficient conditions for such curves to exist as well as…
Relations abéliennes des tissus ordinaires de codimension arbitraire
Daniel Lehmann
We generalize to webs of any codimension results already known in codimension one. Given a holomorphic -web of codimension in an ambiant -dimension…
Courbure des tissus planaires définis implicitement par une équation différentielle polynomiale en y'. Programmation
Jean-Paul Dufour, Daniel Lehmann
The aim of this paper is mainly, after some theoretical explanations, to provide a program on Maple for computing, whatever be d, the curvature of the planar d-web implicitely defi…
Des séries de tissus ordinaires de rang maximum en toute dimension
Jean-Paul Dufour, Daniel Lehmann
In this paper, we define, from a finite set E of functions, a family of holomorphic webs of codimension one in any dimension . We prove that it is sufficient t…
