A Converse to a Theorem of Oka and Sakamoto for Complex Line Arrangements
- Kristopher Williams
Let C1 and C2 be algebraic plane curves in such that the curves intersect in d1 · d2 points where d1, d2 are the degrees of the curves respectively. Oka and Sakamoto proved that π1( C1 U C2)) ≅ π1 ( C1) × π1 (...
