On classical upper bounds for slice genera
Peter Feller, Lukas Lewark
We introduce a new link invariant called the algebraic genus, which gives an upper bound for the topological slice genus of links. In fact, the algebraic genus is an upper bound fo…

Khovanov width and dealternation number of positive braid links
Sebastian Baader, Peter Feller, Lukas Lewark +1
We give asymptotically sharp upper bounds for the Khovanov width and the dealternation number of positive braid links, in terms of their crossing number. The same braid-theoretic t…
