## Abstract A __quasiβkernel__ in a digraph is an independent set of vertices such that any vertex in the digraph can reach some vertex in the set via a directed path of length at most two. ChvΓ‘tal and LovΓ‘sz proved that every digraph has a quasiβkernel. Recently, Gutin et al. raised the question o

## Abstract A vertex set __X__ of a digraph __D__β=β(__V, A__) is a __kernel__ if __X__ is independent (i.e., all pairs of distinct vertices of __X__ are nonβadjacent) and for every __v__ β __V__β__X__ there exists __x__ β __X__ such that __vx__ β __A__. A vertex set __X__ of a digraph __D__β=β(__V
