Categorical constructions in graph theory
The aim of this paper is to present some standard concepts of category theory (like adjoint functors, monads, Cartesian closed categories,...) for graph theorists. As an evidence of fruitful interactions between graph theory and category theory, the monograph ''Combinatorial, algebraic and topological representations of groups, semigroups and categories'' by \textit{A. Pultr} and \textit{V. Trnkova} (1980; Zbl 0418.18004) can be recommended.
