一类(2,5)环面曲线的Alexander多项式

On Alexander Polynomials of Certain (2,5) Torus Curves

M. Kawashima, M. Oka

摘要:

本文在原点O是唯一内奇点,f2 = 0是不可约二次曲线的条件下,计算了(2,5)型环面曲线C的Alexander多项式,C:f(x,y)= f2(x,y)^5 + f5(x,y)^2 = 0.我们表明,亚历山大多项式保持相同的一般环面曲线,只要C是不可约的。

英文摘要:

In this paper, we compute Alexander polynomials of a torus curve C of type (2, 5), C : f(x, y) = f_2(x, y)^5 + f_5(x, y)^2 = 0, under the assumption that the origin O is the unique inner singularity and f2 = 0 is an irreducible conic. We show that the Alexander polynomial remains the same with that of a generic torus curve as long as C is irreducible.
