These are braids coming from maps of formal loops (Spec(C((t))) into a hyperplane complement. These arise naturally in two ways: 1) as links of singularities of plane curves 2) as Stokes data for irregular singularities. It turns out that algebraic braids are quite a restrictive class. I'll explain a complete classification/construction of them. Official event details: https://calendar.usc.edu/event/usc-topology-seminar-quasi-algebraic-braids
