13 p, 351.5 KB Some new results on Darboux integrable differential systems / Ferragut Amengual, Antoni Manel (Universitat Politècnica de Catalunya. Departament de Matemàtica Aplicada I)
We deal with complex planar differential systems having a Darboux first integral H. We present a definition of remarkable values and remarkable curves associated to H and characterize the existence of a polynomial inverse integrating factor for these systems. [...]

9 p, 132.4 KB f-polynomials, h-polynomials and l2-Euler characteristics / Boros, Dan (Otterbein College (Estats Units d'Amèrica). Department of Mathematical Sciences)
We introduce a many-variable version of the f-polynomial and h-polynomial associated to a finite simplicial complex. In this context the h-polynomial is actually a rational function. We establish connections with the l2-Euler characteristic of right-angled buildings. [...]
