Braid groups have a representation theory of wild type, in the sense that there is no known classification schema. Lawrence and Bigelow constructed representations of the braid group on n strands using the configuration space of m points of a n-punctured disc: namely, the braid group acts on the m-th homology group of a particular covering of the configuration space. There is actually an underlying general method to build such homological representations. I will present these methods in this talk.
