Resumen de Exponential integrability of mappings of finite distortion

Tuomo Äkkinen, Kai Rajala

• We consider mappings with exponentially integrable distortion whose Jacobian determinants are integrable over the nn-ball. We show that the boundary extensions of such mappings are exponentially integrable with bounds, and give examples to illustrate that there is not too much room for improvement. This extends the results of Beurling [2], and Chang and Marshall [3], [10] on analytic functions, and Poggi-Corradini and Rajala [14] on quasiregular mappings.
