TitleHomological invariants of Hurwitz equivalence on tuples of simple braids
Abstract
Hurwitz equivalence on tuples of simple braids is studied, which can be used in the study of braided surfaces, surface braids and surface links. In this talk, we define a matrix for a tuple of simple braids by using the first homology classes of a punctured disk. We also introduce some invariants of Hurwitz equivalence on tuples of simple braids by using their matrices.
