### On homogeneous polynomial solutions of generalized Moisil-Théodoresco systems in Euclidean space

(2010) CUBO - A MATHEMATICAL JOURNAL. 12(2). p.145-167- abstract
- Let for s ∈ {0, 1, ...,m+ 1} (m ≥ 2) , R(s)_0,m+1 be the space of s-vectors in the Clifford algebra R_0,m+1 constructed over the quadratic vector space R^0,m+1 and let r, p, q, ∈ N be such that 0 ≤ r ≤ m + 1, p < q and r + 2q ≤ m + 1. The associated linear system of first order partial differential equations derived from the equation ∂W = 0 where W is R^(r,p,q)_0,m+1 valued and ∂ is the Dirac operator in R^m+1, is called a generalized Moisil-Theodoresco system of type (r, p, q) in Rm+1. For k ∈ N, k ≥ 1,MT+(m+1; k; R(r,p,q)_0,m+1), denotes the space of R(r,p,q)_0,m+1-valued homogeneous polynomials W_k of degree k in R^m+1 satisfying ∂W_k = 0. A characterization of W_k ∈ MT is given in terms of a harmonic potential H_k+1 belonging to a subclass of R(r,p,q)_0,m -valued solid harmonics of degree (k + 1) in Rm+1. Furthermore, it is proved that each W_k ∈MT admits a primitive W_k+1. Special attention is paid to the lower dimensional cases R3 and R4. In particular, a method is developed for constructing bases for the spaces MT, for even r.
