Outline of Final Research Achievements |
We wrote the paper " Ribbon disks with the same exterior " and submitted to "Communications in Analysis and Geometry", and it was accepted.In this paper, we constructed infinitely many ribbon disks whose exteriors are the same. The idea to construct is to use annulus twists. Also, we are writing a paper on the enhanced Milnor number with Keiji Tagami.
