引入了一个新的结点不变量,称为函数。它是通过将基本群的不可对角化表示计数到SL2(𝔽q),直到共轭,并形成一个形式的幂级数来定义的,类似于代数几何中的ζ函数。给出了该不变量在一般情况下的结构。研究了环面结的特殊情况,指出了环面结的基本拓扑性质。
An new invariant of a knot, called thezeta-function, is introduced. It is defined by counting the non-diagonalizable representations of the fundamental group into SL2(𝔽q), up to conjugacy, and forming a formal power series, similar to a zeta-function from algebraic geometry. The structure of this invariant in the general case is given. The special case oftorus knots is studied, and basic topological properties are noted.
