Abstract

In this paper we consider operators acting on a subspace of the space L 2 ( m ; m ) of square integrable functions and, in particular, Clifford differential operators with polynomial coefficients. The subspace is defined as the orthogonal sum of spaces s , k of specific Clifford basis functions of L 2 ( m ; m ) . Every Clifford endomorphism of can be decomposed into the so-called Clifford-Hermite-monogenic operators. These Clifford-Hermite-monogenic operators are characterized in terms of commutation relations and they transform a space s , k into a similar space s ' , k ' . Hence, once the Clifford-Hermite-monogenic decomposition of an operator is obtained, its action on the space is known. Furthermore, the monogenic decomposition of some important Clifford differential operators with polynomial coefficients is studied in detail.

AB - In this paper we consider operators acting on a subspace $\mathcal {M}$ of the space $L_2(\mathbb {R}^m;\mathbb {C}_m)$ of square integrable functions and, in particular, Clifford differential operators with polynomial coefficients. The subspace ${\mathcal {M}}$ is defined as the orthogonal sum of spaces ${\mathcal {M}}_{s,k}$ of specific Clifford basis functions of $L_2(\mathbb {R}^m;\mathbb {C}_m)$. Every Clifford endomorphism of ${\mathcal {M}}$ can be decomposed into the so-called Clifford-Hermite-monogenic operators. These Clifford-Hermite-monogenic operators are characterized in terms of commutation relations and they transform a space ${\mathcal {M}}_{s,k}$ into a similar space ${\mathcal {M}}_{s^{\prime }\!,k^{\prime }}$. Hence, once the Clifford-Hermite-monogenic decomposition of an operator is obtained, its action on the space ${\mathcal {M}}$ is known. Furthermore, the monogenic decomposition of some important Clifford differential operators with polynomial coefficients is studied in detail.
