"One is enough"
Abstract:
Using Gabai's recent proof of the 4-dimensional light-bulb theorem, we show that any two homologous surfaces of the same genus embedded with simply-connected complements in a smooth 4-manifold become smoothly isotopic after one stabilization (connected summing with a 2-sphere bundle over the 2-sphere). This is joint work with Auckly, Kim, Ruberman and Schwartz
