Abstract:

We study the validity of (q,p)-Poincare inequalities, q<p, on domains in ’Rⁿ which satisfy a quasihyperbolic boundary condition, i.e. domains whose quasihyperbolic metric satisfies a logarithmic growth condition. In the present paper, we show that the quasihyperbolic boundary condition domains support a (q,p)-Poincare inequality whenever p>p_0, where p₀ is an explicit constant depending on q, on the logarithmic growth condition, and on the boundary of the domain.
