Émilie Coupechoux Résumé En Français

Several kinds of real-world networks can be represented by graphs, in which vertices represent individuals (in social networks), or web pages (in the case of the World Wide Web), to mention only these examples. Each edge of the graph stands for an interaction between vertices: in social networks, an edge is present between two vertices if the individuals they represent are friends; in the World...

The NA49 detector with its wide acceptance coverage and extensive particle iden­ tification capabilities, offers a general purpose instrument for the study of hadronic interactions which is today unique in the SPS energy range. After a first phase of exploratory investigation of lead-lead interactions at the high­ est SPS energy, the collaboration is planning to extend its experimental programm...

— We describe explicitly the moduli spaces M pst g (S, E) of polystable holomorphic structures E with det E ∼= K on a rank two vector bundle E with c1(E) = c1(K) and c2(E) = 0 for all minimal class VII surfaces S with b2(S) = 1 and with respect to all possible Gauduchon metrics g. These surfaces S are nonelliptic and non-Kähler complex surfaces and have recently been completely classified. When...

In this paper we consider the question of determining the geometric genera of irreducible curves lying on a very general surface S of degree d > 5 in P (the cases d 6 4 are well known). For any d > 4 we introduce the set Gaps(d) of all non–negative integers which are not realized as geometric genera of irreducible curves on a very general surface of degree d in P. We prove that Gaps(d) is finit...
