本文致力于Reidemister扭转的研究。它是n维流形的分段线性不变量,最初由Reidemister,Franz和De Rham定义。1985年,Casson利用基本群的$SU(2)$-表示空间上的一个漂亮构造,定义了同调3-球面的一个有趣的拓扑不变量。后来,约翰逊利用里德迈斯特扭转作为其基本成分,发展了与卡森的理论类似的理论。对于$SL(2;C)$-不可约表示,他还得到了Brieskom同调3-球面的Reidemister挠的一个显式公式。在这篇文章中,我们称这类Reidemister挠度为$SL(2;C)$-挠度跟随Johnson。设$M_{n}$是环面$(p,q)$-纽结上的$1/n$-运算得到的3-流形。它是Brieskom同调3-球面
This paper is devoted to the study of the Reidemeister torsion. It is a piecewise linear invariant for n-dimensional manifolds and originally defined by Reidemeister, Franz and de Rham. In 1985 Casson defined an interesting topological invariant of homology 3-spheres by making use of a beautiful construction on the space of $SU(2)$-representations of the fundamental group. Later Johnson developed a similar theory of Casson’s one by using the Reidemeister torsion as its essential ingredient. He also derived an explicit formula for the Reidemeister torsion of Brieskom homology 3-spheres for $SL(2;C)$-irreducible representations. In this paper, we call this type Reidemeister torsion the $SL(2;C)$-torsion following Johnson. Let $M_{n}$ be a 3-manifold obtained by the $1/n$-surgery on a torus $(p, q)$-knot. It is a Brieskom homology 3-sphere
