关于Kauffman关于交错环和伪交错环的一个猜想

On a Conjecture by Kauffman on Alternative and Pseudoalternating Links

Marithania Silvero

摘要:

已知替代链路是伪交替链路。1983年,路易斯·考夫曼(Louis Kauffman)证实这两个类是相同的。本文证明了Kauffman猜想对第一个贝蒂数至多为2的环成立。然而,当这个值增加时,一般情况下这是不正确的,因为我们也通过找到两个反例来证明:一个链接和一个结,其第一个贝蒂数分别等于3和4。

英文摘要:

It is known that alternative links are pseudoalternating. In 1983 Louis Kauffman conjectured that both classes are identical. In this paper we prove that Kauffman Conjecture holds for those links whose first Betti number is at most 2. However, it is not true in general when this value increases, as we also prove by finding two counterexamples: a link and a knot whose first Betti numbers equal 3 and 4, respectively.
