Abstract
Let Ω be a pseudoconvex domain in \(\mathbb {C}^{n}\) with smooth boundary bΩ. We define general estimates \((f\text {-}\mathcal {M})^{k}_{\Omega }\) and \((f\text {-}\mathcal {M})^{k}_{b{\Omega }}\) on k-forms for the complex Laplacian □ on Ω and the Kohn–Laplacian □ b on bΩ. For 1 ≤ k ≤ n−2, we show that \((f\text {-}\mathcal {M})^{k}_{b{\Omega }}\) holds if and only if \((f\text {-}\mathcal {M})^{k}_{\Omega }\) and \((f\text {-}\mathcal {M})^{n-k-1}_{\Omega }\) hold. Our proof relies on Kohn’s method in Kohn (Ann. Math. 156(2), 213–248, 2002).
