Join theorem for real analytic singularities
Kazumasa Inaba
Let f_1 and f_2 be real analytic germs of independent variables. In this paper, we assume that f_1, f_2 and f = f_1 + f_2 satisfy a_f -condition. Then we show that the tubular Miln…

On the number of cusps of deformations of complex polynomials
Kazumasa Inaba
Let f be a 1-variable complex polynomial such that f has a singularity at the origin. In the present paper, we show that there exists a deformation of f which has only fold singula…

Topology of mixed hypersurfaces of cyclic type
Kazumasa Inaba, Masayuki Kawashima, Mutsuo Oka
We study a simplicial mixed polynomial of cyclic type and its associated weighted homogeneous polynomial. In the present paper, we show that their links are diffeomorphic and their…
