Weighted and boundary l p estimates for solutions of the $\partial$ -equation on lineally convex domains of finite type and applications

Abstract

We obtain sharp weighted estimates for solutions of the equation $\partial$ u = f in a lineally convex domain of finite type. Precisely we obtain estimates in the spaces L p ($\Omega$,$\delta$ $\gamma$), $\delta$ being the distance to the boundary, with two different types of hypothesis on the form f : first, if the data f belongs to L p $\Omega$,$\delta$ $\gamma$ $\Omega$ , $\gamma$ > --1, we have a mixed gain on the index p and the exponent $\gamma$; secondly we obtain a similar estimate when the data f satisfies an apropriate anisotropic L p estimate with weight $\delta$ $\gamma$+1 $\Omega$. Moreover we extend those results to $\gamma$ = --1 and obtain L p ($\partial$ $\Omega$) and BMO($\partial$ $\Omega$) estimates. These results allow us to extend the L p ($\Omega$,$\delta$ $\gamma$)-regularity results for weighted Bergman projection obtained in [CDM14b] for convex domains to more general weights.
