The 4-Dimensional Light Bulb Theorem
David Gabai, Department of Mathematics, Princeton University
We generalize the classical light bulb theorem to four dimensions. I.e. a smooth 2-sphere in S^2\times S^2 that intersects S^2\times 0 once and is homologous to 0\times S^2 is smoothly isotopically standard.
