    • Fundamental group and cycle space of dual graphs and applications 

      Jaradat, M.M.M. ( Elsevier , 2010 , Article)
      In this work, we study the fundamental group of dual graph of a planar graph. Moreover, we show that a planar graph G has no cut vertex if and only if N(Π(D(G))) = N(Π(D(G − v))) − 1 for any v ∈ V(G). Some applications ...
