Abstract: | By definition, the domain Ω ??n belongs to the class EW p l if there exists a continuous linear extension operator . An example is given of a domain Ω ??2 with compact closure and Jordan boundary, having the following properties: (1) The curve ?Ω is not a quasicircle, has finite length and is Lipschitz in a neighborhood of any of its points except one. (2) Ω ε EW p 1 for p<2. and Ω ? EW p 1 for p?2. (3) for p>2 and for p?2. |
