“…Pommerenke [13] shows that (1.3) holds for 3 4 < p < 3.399. In this aspect, we refer to read [12], [4], [5] . Our work, is in part an elaboration of P. Hajlasz's idea,when he constructed a bounded domain Ω ⊂ R 2 with the cone property and proved that u(z) = ℑ(z −1/2 + i 2 ) is a harmonic function in Ω and belong to W 1,p 0 (Ω) for all 1 ≤ p < 4 3 , and shown that the Dirichlet problem for the Laplace equation cannot be in general solved with the boundary data in W 1,p (Ω), for all p < 4.…”
