Abstract

There is a homomorphism of associative superalgebras from the enveloping algebra of the orthosymplectic Lie superalgebra osp(12)\mathfrak{osp}(1|2) to the Weyl-Clifford superalgebra W(2nn)W(2n|n) with 2n2n even Weyl algebra generators and nn odd Clifford algebra generators. Under this homomorphism, the positive odd root vector xosp(12)x\in\mathfrak{osp}(1|2) is sent to the Dirac operator γμμW(2nn)\gamma^\mu\partial_\mu\in W(2n|n) and generates a left ideal II. The corresponding reduction (super)algebra, denoted ZnZ_n, is the normalizer of II in W(2nn)W(2n|n) modulo II. By construction, ZnZ_n acts on the space of all Clifford algebra-valued polynomial solutions to the (massless) Dirac equation. In this paper, we find a complete presentation of (a localization of) this so-termed Dirac reduction algebra. Furthermore, we use the Dirac reduction algebra to generate all polynomial solutions to the Dirac equation in nn-dimensional flat spacetime.
