Positive braid closures and taut foliations

Geometric Topology 2026-02-23 v1

Abstract

We study taut foliations on the complements of non-split positive braid closures in S3S^3. If LL is such a link with components L1,,LnL_1,\ldots,L_n and at least one component is not the unknot, then the Dehn surgery along a multislope (s1,,sn)Qn(s_1,\ldots,s_n)\in\mathbb{Q}^n satisfying si<2g(Li)1s_i<2g(L_i)-1 for i=1,2,,ni=1,2,\ldots, n yields a non-L-space that admits a co-oriented taut foliation.
