On Vosperian and Superconnected Vertex-Transitive Digraphs
(Springer, 2013)We investigate the structure of a digraph having a transitive automorphism group where every cutset of minimal cardinality consists of all successors or all predecessors of some vertex. We give a complete characterization ... -
Small cutsets in arc-transitive digraphs of prime degree
(Elsevier, 2013)We give an upper bound for the size of non-trivial sets that have small boundary in a family of arc-transitive digraphs. We state the exact size for these sets in case of prime degree. We also give a lower bound for the ...
