Complex classification of singularities of reducible septic curves
Abstract
There are 163 types of quadruple points, 139 types of quintuple points, and 25 types of sextuple points for complex reducible septic curves. 20 types of double points and 69 types of triple points are constructed for complex reducible septic curves. Thus, 417 types of singularities are exhibited.
