Abstract: | A new proof is given for a theorem by V. G. Maz'ya. It gives a necessary and sufficient condition on the open set Ω inR
N
for the functions inW

(Ω) to have the ordinary norm equivalent to the norm obtained when including only the highest order derivatives in the definition.
The proof is based on a kind of polynomial capacities, Maz'ya capacities. |
