Γ-Species and the Enumeration of $k$-Trees

[摘要] We study the class of graphs known as $k$-trees through the lens of Joyal’s theory of combinatorial species (and a extension known as 'Γ-species' which incorporates data about 'structural' group actions). This culminates in a system of recursive functiona
