新的链环不变量和多项式(I),定向情形

New link invariants and Polynomials (I), oriented case

Zhiqing Yang

摘要:

给定任何有向链接图,构造两种新的纽结不变量。它们满足一些广义的绞关系。每个不变量的系数来自于一个交换环。这些环的同态和表示定义了新的链接不变量。例如,三个变量的HOMFLYPT多项式。在这个意义上,第一类不变量是HOMFLYPT多项式的推广。这些不变量也可以通过修改和参数化来获得更强大的不变量。例如,修改后的第一类不变量区分突变体,参数化的不变量产生交叉数的信息。

英文摘要:

Given any oriented link diagram, two types of new knot invariants are constructed. They satisfy some generalized skein relations. The coefficients of each invariant is from a commutative ring. Homomorphisms and representations of those rings define new link invariants. For example, the HOMFLYPT polynomial with three variables. In this sense, type one invariant is a generalization of the HOMFLYPT polynomial. Those invariants can also be modified by writhe and parameterized to get more powerful invariants. For example, the modified type one invariant distinguishes mutants, and the parameterized invariants produces information for crossing number.
