摘要
研究了素数阶循环图的基本性质.提出寻求有效参数构造正则循环图的新方法.得到3个经典Ramsey数的新下界:R(8,16)≥578,R(8,17)≥642,R(8,18)≥678.这3个结果填补了关于Ramsey数的上下界表中的3个空白.
Basic character of prime order cyclic graph is studied.Some skills for seeking effective parameters to structure regular cyclic graph are released.New lower bounds of three classical Ramsey numbers are obtained as follows: R(8,16)≥578,R(8,17)≥642,R(8,18)≥678. These three results fill in three blanks in the table of upper and lower bounds on Ramsey numbers.
