The choice of hypersurface is 35 coefficients (c_i). Then on a standard A^4 patch of Gr(2,4), you have 4 variables. The equations for one line to lie on the hypersurface will be a system of 5 equations in the (c_i). Do the same thing on the other patches of Gr(2,4). What happens if you turn on your computer and try to "randomly" find (c_i) so that none of these equations have solutions? Conics will of course be harder still, but maybe manageabl.e | |
