“…We continue here the study of the problem for (0, 1)-forms on model domains, focusing on the bi-disc, Ω = D 1 × D 2 ∈ C 2 , where D 1 ⊂ C and D 2 ⊂ C are defined by the equations r 1 < 1 and r 2 < 1, respectively, where r j = |z j |, j = 1, 2. The existence of a solution in L 2 (Ω) is given by Hörmander [6]. We shall see singularities only occur on the distinguished boundary, ∂D 1 × ∂D 2 .…”
