Accordingly, the unit imaginary is dropped in what follows, and an entirely real formulation is given. 2 The Geometrisation of Berezin Calculus The basis of Grassmann/Berezin calculus is described in many sources. Berezin's \The method of second quantisation" 35] is one of the earliest and most cited texts, and a 30 useful summary of the main results from this is contained in the Appendices to 39]. More recently, Grassmann calculus has been extended to the eld of superanalysis 51, 52], as well as in other directions 53, 54].

96) we nd that (a b) = xisi ; yiri (3:97) which is the component form of the symplectic norm in <2n. 69). The di erences between the Lie algebras of GL(n,R) and U(n) are due solely to the metric signature of the underlying vector space which generates the bivector algebra. It follows that both Lie algebras have the same complexi cation, since complexi cation removes all dependence on signature. In the theory of the classi cation of the semi-simple Lie algebras, the complexi cation of the su(n) and sl(n,R) algebras is denoted An;1 .

It follows that the symmetry group is constructed entirely from the double sided action of the elements of the spin group which satisfy MJ = JM: (3:62) These elements a ord a spin group representation of the unitary group. 62) requires that, for a rotor R simply connected to the identity, the bivector generator of R commutes with J . The Lie algebra of a unitary group is therefore realised by the set of bivectors commuting with J , which we have seen are also eigenbivectors of J . Given an arbitrary bivector B , therefore, the bivector BJ = B + J (B ) (3:63) is contained in the bivector algebra of u(p,q).
