## Abstract A __k__‐__digraph__ is a digraph in which every vertex has outdegree at most __k__. A $(k \vee l)$‐__digraph__ is a digraph in which a vertex has either outdegree at most __k__ or indegree at most __l__. Motivated by function theory, we study the maximum value Ξ¦ (__k__) (resp. $\Phi^{\v
