| Sep 23, 2016 at 22:51 | comment | added | paul garrett | In addition to @JimHumphreys observations about pseudo-primitive versus modern approaches, there is a middle ground: the Howe/theta-correspondence pairings, aka "Segal-Shale-Weil repn", of symplectic groups over global, local, or finite fields, (via Stone-vonNeumann theorem and such) do also shed light on the repn theory of $SL_2(\mathbb F_q)$. Depending on one's sequel to this, it might be more interesting/relevant than the Deligne-Lusztig theory (which does, indeed, give a very complete answer in the literal finite-field case). | |
