Annihilators for harmonic differential forms via Clifford analysis
The authors completely describe the annihilators of harmonic differential forms using Clifford algebras and the methods introduced by the authors in [Adv. Appl. Clifford Algebr. 17, No. 4, 589--610 (2007; Zbl 1134.30336)]. Their tools are different from methods used by \textit{B. Gustafsson} and \textit{D. Khavinson} [J. Math. Sci., New York 92, No. 1, 3600--3612 (1998); translation from Zap. Nauchn. Semin. POMI 232, 90--108 (1996; Zbl 0891.30029)]. The idea of using Clifford algebras is coming from the result that there exists a one-to-one correspondence between harmonic differential forms in the sense of Hodge and harmonic Clifford valued multivector fields (see [\textit{R. Abreu-Blaya, J. Bory-Reyes, R. Delanghe} and \textit{F. Sommen}, Bull. Belg. Math. Soc. - Simon Stevin 11, No. 1, 95--110 (2004; Zbl 1063.30045)]).
