Knotting of Algebraic Curves in CP2

摘要

I construct "fake algebraic curves" in Cp2Cp^2. More precisely, for any k>2, I construct infinitely many pairwise smoothly non-isotopic (and moreover not ambient diffeomorphic) smooth surfaces FCp2F\subset Cp^2 homeomorphic to a non-singular algebraic curve of degree 2k, realizing the same homology class as such a curve and having abelian fundamental group of the complement Cp2FCp^2-F. This gives an answer to Problem 4.110 of Kirby's list.
