Hi, All: Sorry if this is off-topic, but I did not know where else to ask. These are geometric/topological terms, so I thought it'd make sense to ask here: I am reading a math paper in French, and I'm having trouble : 1)Cellulation de Contact . Cellules. I suspect this has to see with cellular homology , and decomposition into cells (as in CW-complexes ) 2) Decoupage, as in: ...S est une surface e-convexe, dont le decoupage est fourni par K. Thanks. If necessary, I'll delete and post somewhere else. EDIT/P.S: For the sake of context, the paper is on Contact Structures and Open Book Decompositions. Sorry, I cannot find a link for it online.
