Abstract

The necessary appearance of Clifford algebras in the quantum description of fermions has prompted us to re-examine the fundamental role played by the quaternion Clifford algebra, C0,2. This algebra is essentially the geometric algebra describing the rotational properties of space. Hidden within this algebra are symplectic structures with Heisenberg algebras at their core. This algebra also enables us to define a Poisson algebra of all homogeneous quadratic polynomials on a two-dimensional sub-space, \(\mathbb{F}^{a}\) of the Euclidean three-space. This enables us to construct a Poisson Clifford algebra, ℍF, of a finite dimensional phase space which will carry the dynamics. The quantum dynamics appears as a realisation of ℍF in terms of a Clifford algebra consisting of Hermitian operators.
