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).

"Web3 The motivic Hilbert zeta function When Xis a singular curve, the ZSym X (t) does not capture much information about the singularities. In fact, ZSym X (t) depends only on the number of branches at each singular point. Example 3.1. Let Xbe a projective rational curve with a single cusp. Then the nor-malization P1!X is a cut and paste isomorphism. " - Hilbert schemes of singular curves
