Singular 2 webs and Polar Curves
Fernando Etayo
A 2-web in the plane is given by two everywhere transverse 1-foliations. In this paper we introduce the study of singular 2-webs, given by any two foliations, which may be tangent…

Connections functorially attached to almost complex product structures
Fernando Etayo, Rafael Santamaría
Manifolds endowed with three foliations pairwise transversal are known as 3-webs. Equivalently, they can be algebraically defined as biparacomplex or complex product manifolds, i.e…
