Feynman graphs lie in the heart of perturbative Quantum Field Theory, as a combinatorial device for computing probabilities of various interactions. They are deeply related to important algebraic structures : Hopf algebras, homological algebra, categories,... which can shed some light on the underlying physics, as shown e.g. by the work of A. Connes and D. Kreimer, using the Hopf algebra structure in renormalization. The present meeting aims to let specialists of graphs under these various aspects to meet together.
