Roughly speaking, Deligne showed that any such family obeys a ""generalized Sato-Tate law, "" and that figuring out which generalized Sato-Tate law applies to a given family amounts essentially to computing a certain complex semisimple (not necessarily connected) algebraic group, the ""geometric monodromy | ||
