A sequence of [Formula: see text]-polynomials [Formula: see text] of virtual knots [Formula: see text] was defined by Kaur et al. in 2018. These polynomials have been expressed in terms of index value of crossing and [Formula: see text]-writhe of [Formula: see text]. By the construction, [Formula: see text]-polynomials are generalizations of Kauffman’s Affine Index Polynomial, and are invariants of virtual knot [Formula: see text]. We present values of [Formula: see text]-polynomials of oriented virtual knots having at most four classical crossings in a diagram.

列表虚拟结的 F 多项式

Kaur等人定义了一系列[公式:见文本]-多项式[公式:见文本]的虚拟结[公式:见文本]。2018年。这些多项式已经用交叉指数值和[公式:见文]-writhe的[公式:见文]来表示。通过构造,[公式:见正文]-多项式是考夫曼仿射指数多项式的推广,并且是虚拟结的不变量[公式:见正文]。我们给出了[公式:见文本]-在图中最多具有四个经典交叉点的定向虚拟结的多项式的值。
