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

M. Kawashima, M. Oka

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…

Topology of polar weighted homogeneous hypersurfaces

Mutsuo Oka

Polar weighted homogeneous polynomials are the class of special polynomials of real variables $x_{i}, y_{i}, i = 1, ..., n$ with $z_{i} = x_{i} + - 1 y_{i}$ , which enjoys a "polar action". In…
