abstract
We prove certain $L^p$ Sobolev-type inequalities for twisted differential forms on real (and complex) manifolds for the Laplace operator $\Delta$, the differential operators $d$ and $d^*$, and the operator $\bar\partial$. A key tool to get such inequalities are integral representations for twisted differential forms. The proofs of the main results involves certain uniform estimate for the Green forms and their differentials and codifferentials, which are also established in the present work. As applications of the uniform estimates, using Hodge theory, we can get an $L^{q,p}$-estimate for the operator $d$ or $\bar\partial$. Furthermore, we get an improved $L^2$-estimate of H\"ormander on a strictly pseudoconvex open subset of a K\"ahler manifold.

Siu's curvature positivity and $L^2$ extension theorems for $(p,q)$-forms
Siu's curvature operator A^E_{p,q} is characterized by an optimal L2 estimate and yields an Ohsawa–Takegoshi extension theorem for (p,q)-forms and local freeness of higher direct images.
