Title

From combinatorial species to general differential 2-rigs

Abstract

After a quick presentation of the works of Loregian on differential 2-rigs and of other authors on combinatorial species, we will study if we can use similar combinatorial methods to solve differential equations or count their solutions in a more general context. We will build various examples of differential 2-rigs, in which differential equations behave in fundamentally different ways.
