Quasipositive braids and connected sums

Abstract

We prove that the connected sum of two links is quasipositive if and onlyif each summand is quasipositive. The prove is based on the filling disk technique

5 pages. In v3 the numbering of theorems, lemmas etc. is changed according to the published version. No other difference between v2 and v3
