Cobordisms of graphs. A sliceness criterion for stably odd knots and related results on cobordisms
arXiv:1708.07365
Abstract
In [D.A. Fedoseev, V.O. Manturov, A sliceness criterion for odd free knots,arXiv:1707.04923], the authors proved a sliceness criterion for odd free knots: free knots with odd chords. In the present paper we give a similar criterion for stably odd free knots. Some additional results on knot sliceness and cobordism are given.
