Ordinary and calibrated differential operators Application to curvilinear webs

Daniel Lehmann

We study the space of the solutions $s$ of any system of partial differential equations $D (j^{k} s) = 0$ defined by a linear and homogeneous differential operator $D : J^{k} E \to F$ of a…

Rank of ordinary webs in codimension one. An effective method

Jean Paul Dufour, Daniel Lehmann

We are interested by holomorphic $d$ -webs $W$ of codimension one in a complex $n$ -dimensional manifold $M$ . If they are ordinary, i.e. if they satisfy to some condition of generici…
