| Sumario: | In 1994, Astala published his celebrated Area Distortion Theorem for quasiconformal mappings, a groundbreaking result that allowed a number of new results within this area of Analysis to appear during the last two decades. We focus on the consequences that it has on the distortion of Hausdorff measure. We follow in particular the approach of the article by Lacey, Sawyer and Uriarte-Tuero to the distortion of content, clarifying some point and changing the approach of the bounds for the Beurling transform, where we take the more classical approach of the article by Astala, Clop, Tolsa, Uriarte-Tuero and Verdera instead. |
