THE BOUND OF THE MAXIMUM NUMBER OF END VERTICES OF SPANNING TREES
《Chinese Science Bulletin》1988年第14期1149-1151,共3页张福基 陈治柏 
Schuster, Cai Maocheng and Lin Yixun studied the interpolation theory for the number of end vertices of spanning trees of graph. Zhang Fuji and Guo Xiaofeng obtained the related result of digraph. This paper is devote...

2-CONNECTED K-REGULAR GRAPHS ON AT MOST 3k+3 VERTICES TO BE HAMILTONIAN
《Chinese Science Bulletin》1985年第9期1269-,共1页朱永津 刘振宏 俞正光 
B. Jackson (Jackson, B. Hamilton cycles in regular 2-connected graphs, J. Comb. Theory(B),29(1980), 27—46) has shown that 2-connected κ-regular graphs on at most 3κ vertices are Hamiltonian. We improved Jackson’s ...

THE NUMBERS OF VERTICES WITH LOW DEGREE IN CRITICALLY h-CONNECTED GRAPHS
《Chinese Science Bulletin》1985年第3期422-,共1页苏健基 
Let G be a critically h-conneeted noncomplete graph. Hamidoune proved that G contains at least two vertices of degree not exceeding 3/2h-1(Dis-orete Mathematics, 32 (1980), 257—262).
