Resumen inglés | We continue an investigation started in a preceding paper. We discuss tha classical result of Carleson connecting Carleson measures with the ∂-equation in a slightly more abstract framework than usual. We also consider a more recent result of Peter Jones which shows the existence of a solution for the ∂-equation, which satisfies simultaneously a good L∞ estimate and a good L1 estimate. This appears as a special case of our main result which can be stated as follows: Let (Ω, A, μ) be any measure space. Consider a bounded operator u: H1 → L1(μ). Assume that on one hand u admits an extension u1: L1 → L1(μ) bounded with norm C1, and on the other hand that u admits an extension u∞: L∞ → L∞(μ) bounded with norm C∞. Then u admits an extension u' which is bounded simultaneously from L1 into L1(μ) and from L∞ into L∞(μ) and satisfies ||u': L∞ → L∞(μ)|| ≤ C C∞ ||u': L1 → L1(μ)|| ≤ C C1 where C is a numerical constant. |
