TitleOn slope genera of knotted tori in the 4-space
Abstract
We investigate genera for the slopes of a knotted torus in the 4-sphere analogous to the genus of a classical knot. We compare various formulations of this notion, and use this notion to study the extendable subgroup of the mapping class group of the knotted torus. This is a joint work with Liu Yi, Ni Yi and Sun Hongbin.
