摘要
分别研究了一类带有Hamiltonian路和带有Hamiltonian圈的有向图的基本有圈性(essential cyclicity),给出了这种有向图的Laplacian谱,表明这些图具有全实的Laplacian谱.
The essential cyclicity of the digraphs with a Hamiltonian path and a Hamiltonian cycle respectively have been investigated and their Laplacian spectra was also fully presented,which imply that the digraphs have completely real Laplacian spectrum.
