Smoothly knotted and topologically unknotted nullhomologous surfaces in 4-manifolds (2005.11696v3)
Published 24 May 2020 in math.GT
Abstract: We point out that recent constructions of inequivalent smooth structures yield a manufacturing procedure of infinite sets of pairwise smoothly non-isotopic nullhomologous 2-tori and spheres inside a myriad of 4-manifolds. The corresponding infinite set consists of topologically isotopic surfaces that topologically bound a handlebody in several instances.
