“…Once the (virtual) copy of the semisimple Lie algebra Gal ℓ (p, q) is found, explicit expression for the Casimir operators can be immediately deduced, in its unsymmetrized analytic form, by means of the well known trace methods (see e.g. [25,26,33,34,35,36,37]). To this extent, let {d, h, c, e i,j , p n,k } be the coordinates in Gal ℓ (p, q) * and let d, h, c, e i,j , p n,k denote the analytical counterpart of the operators in (20).…”
