Resumen de Homeomorphisms of finite distortion: discrete length of radial images
Pekka Koskela 
, Tomi Nieminen
We study homeomorphisms of finite exponentially integrable distortion of the unit ball Bn onto a domain O of finite volume. We show that under such a mapping the images of almost all radii (in terms of a gauge dimension) have finite discrete length. We also show that our dimension estimate is essentially sharp.
