[1]中给出了Euler环游图Eu(G)的定义
并证明了Eu(G)具有边-Hamilton性。[2]中证明了Eu(G)是正则图。本文得到如下结果
对|V(Eu(G)|≥2
Eu(G)的连通度恰好等于其正则度数。
In paper [1]
the authors gave a definition of Euler tour graph E. (G) toan Eulerian graph without loops
which may have multiple edges
and provedthat E_■(G) is edge-Hamiltonian. Paper [2] proved that E_■(G) is a regular graph. Now
we discuss the cennectivity of Euler tour graphs
and get thefollowing conclusion. Let Q ={v|v∈V(G) and dG(v)≥4}■φ
tv=dG(v)/2. and α(G)=sum from v∈0 to tv (tv-1) 2
then the connectivity of E_■ (G) is equal to its regular degree α(G).
