Legendrian graphs and quasipositive diagrams
Sebastian Baader, Masaharu Ishikawa
In this paper we clarify the relationship between ribbon surfaces of Legendrian graphs and quasipositive diagrams by using certain fence diagrams. As an application, we give an alt…

Moebius bands with a quasipositive fibred hole
Sebastian Baader
We prove that every knot in the 3-space bounds an embedded punctured Moebius band whose other boundary component is a quasipositive fibred knot.

Construction of non-alternating knots
Sebastian Baader
We investigate the behaviour of Rasmussen's invariant under the sharp operation on knots and obtain a lower bound for the sharp unknotting number. This bound leads us to an int…
