Families of elliptic curves over the four-pointed configuration space and exceptional sequences for the braid group on four strands
William Y. Chen, Nick Salter
We show that the configuration space of four unordered points in with barycenter 0 is isomorphic to the space of triples , where is an elliptic curve, $Q\…
