Abstract

Every $L$ -space knot is fibered and strongly quasi-positive, but this does not hold for $L$ -space links. In this paper, we use the so called H-function, which is a concordance link invariant, to introduce a subfamily of fibered strongly quasi-positive $L$ -space links. Furthermore, we present an infinite family of $L$ -space links which are not quasi-positive.
