Let $M$ be a smooth real hypersurface in complex space of dimension $n$, $n\ge 3$, and assume that the Levi-form at $z_0$ on $M$ has at least ($q+1$)-positive eigenvalues, $1\leq q\leq n-2$. We estimate solutions of the local $\dibar$-closed extension problem near $z_0$ for $(p,q)$-forms in Sobolev spaces. Using this result, we estimate the local solution of tangential Cauchy-Riemann equation near $z_0$ in Sobolev spaces.
Keywords: tangential Cauchy-Riemann equation, boundary holomorphic forms
