WebOne feature is atranslation operator T on the Hilbert space of states having nice algebraic properties. Let P = P 0 +P 1 be the Hermitian energy-momentum operator. We switch to the light-cone coordinates and write P = P 0 +iP 1, P = P 0-iP 0. Now let Q be the conjugate of P by inversion x !-x=jxj2 which is a conformal map. Then T = 1 2 (P+[P,Q]-Q). WebThese Hilbert modular varieties can be considered as higher-dimensional analogues of Teichmu¨ller curves. We also examine curves whose Jacobians admit real multiplication, and show their eigenforms are always primitive. Real multiplication. Let K be a totally real number ﬁeld of degree g over Q.
