A Modified Dold-Lashof Construction that Does Classify H-Principal Fibrations.
A note on Lie algebroids which arise from groupoid actions
An approach to shape covering maps.
In this note we give an approach to shape covering maps which is comparable to that of *-fibrations (Mardesic and Rushing (1978)). The introduced notion conserves some important properties of usual covering maps.

Characteristic Homomorphisms of Regular Lie Algebroids
Classes caractéristiques des couples de sous-fibrés lagrangiens
La classe de Maslov, classe de cohomologie entière de degré 1, définie sur un fibré vectoriel symplectique muni de deux champs de plans lagrangiens, est une obstruction à leur transversalité. L’objet de ce travail est de construire explicitement, en termes de formes différentielles, des obstructions cohomologiques analogues (de degré supérieur). On étudie de ce point de vue les sous-variétés lagrangiennes de .
