報(bào)告人簡(jiǎn)介：

                    Loic Foissy is a professor at the University of the Littoral Cote d’Opale, France. His research domain is Algebraic Combinatorics. More precisely, He works on combinatorial Hopf algebras, operads and their applications.

報(bào)告摘要：

                    We will present the main aspects of the theory of species:definitions, operations on species (sum, product, composition), combinatorial applications (enumeration results, construction of combinatorial objects), and important examples (graphs, posets...).We will then develop the links with the theory of operads and with the theory of combinatorial Hopf algebras, using various functors.
