Corrected a horrible error about max compact

reworked to introduce name "symmetric space"

I ask because we can define the same action on the space of forms whose imaginary part is positive-definite. If we then pick a basis and pretend that the transpose of an element makes sense then we find the Siegel half-plane in there. | |
