(A, ℬ)-kernels and Sands, Sauer and Woodrow’s theorem

Let D = (V(D), A(D)) a digraph. Consider the set PD= {P : P is a non trivial finite directed path in D} and let A and ℬ two subsets of PD. A subset N of V(D) is said to be an (A, ℬ)-kernel of D if (1) for every subset {u, v} of N there exists no uv-directed path P such that P∈A(N is A-independent) a...
