Resum
We derive equations for the modular curve X-ns(11) associated to a non-split Cartan subgroup of GL(2)(F-11). This allows us to compute the automorphism group of the curve and show that it is isomorphic to Klein's four group We derive equations for the modular curve X-ns(11) associated to a non-split Cartan subgroup of GL(2)(F-11).
