Author’s abstract: In this paper we study the duality of the harmonic spaces on the annulus $$\Omega = \Omega_{1} \setminus \overline{\Omega^{-}}$$ between two pseudoconvex domains with $$\Omega^{-} \subset\subset \Omega_{1}$$ in $$\mathbb{C}^{n}$$ and the Bergman spaces on $$\Omega^{-}$$. We show that on the annulus $$\Omega$$, the space of harmonic forms for the critical case of $$(0,n-1)$$-forms is infinite dimensional and it is dual to the Bergman space on the pseudoconvex domain $$\Omega^{-}$$. The duality is further identified explicitly by the Bochner-Martinelli transform, generalizing a result of L. Hörmander [Ann. Inst. Fourier 54, No. 5, 1305–1369 (2004; Zbl 1083.32033)].
