几乎恰当链环

Almost adequate link

定义了几乎恰当链环,给出了几乎恰当链环与其镜面像之间的关系;利用状态链的方法证明了A-几乎恰当链环的Kauffman尖括号多项式的最高次幂以及B-几乎恰当链环的最低次幂的表达式.

In this paper,a new class of links is given,which is called almost adequate link,in the first part,the conclusion is drawn：if a link K is almost A-adequate,then,the mirror image of K is almost B-adequate;the second part,by using the state links,the main result is provided：the highest degree in the Kauffman polynomial of almost A-adequate links and the lowest degree in the Kauffman polynomial of almost B-adequate links.
