Dear all,

I wish you an happy new year 2004. Here are two announcements:

One new preprint:

Title: S-homotopy as an analogue of homotopy of spaces

Abstract:  We check that there exists a structure of model category on the
category of flows whose weak equivalences are the S-homotopy equivalences.
This model structure is simplicial, but not topological.

Comments: new results about globular complexes added ; one technical proof
posponed to the appendix
