• Resumen

  • We describe some new ways to construct saturated fusion subsystems, including, as a special case, the normalizer of a set of components of the ambient fusion system. This was motivated in part by Aschbacher’s construction of the normalizer of one component, and in part by joint work with three other authors where we had to construct the normalizer of all of the components.
