We will look at graphs with conflicts (conflict is a pair of edges can not simultaneously be part of the same subgraph), in which we will study different types of problems related to the existence of subgraphs without conflict. The nature of the problems is both combinatorial and algorithmic. Our guideline is the notion of connectivity. We will see several results, simple without conflict, are no longer when adding conflicts. We will present exact algorithms (not polynomial), \mathcal{N P}-completeness results and sufficient conditions ensuring the existence of certain objects (spanning tree, path and Hamiltonian cycle) without conflict.Nous nous intéresserons aux graphes avec conflits (un conflit est une paire d’arêtes ne pouvant pas simul...
