Bikei、Involutory Biracks和无向链接不变量
Bikei, Involutory Biracks and unoriented link invariants
摘要：
我们确定了一个子类的biracks定义计数不变量的无方向的链接，我们称之为对合biracks。特别是，birack秩N=1的对合birack是biquandles，我们称之为bikei。我们定义计数不变量的无方向的经典和虚拟的链接使用有限对合birack，我们给出了一个例子的非对合birack的计数不变量检测的不可逆性的虚拟结。
英文摘要：
We identify a subcategory of biracks which define counting invariants of unoriented links, which we call involutory biracks. In particular, involutory biracks of birack rank N=1 are biquandles, which we call bikei. We define counting invariants of unoriented classical and virtual links using finite involutory biracks, and we give an example of a non-involutory birack whose counting invariant detects the non-invertibility of a virtual knot.
