Streszczenie

We establish inequalities for Green functions on general bounded piecewise Dini-smooth Jordan domains in $\mathbb {R}^2$. This enables us to prove a new version of the 3G Theorem which generalizes its previous version given in [M. Selmi, Potential Anal. 13 (2000)]. Using these results, we give a comparison theorem for the Green kernel of $\Delta $ and the Green kernel of $\Delta -\mu $, where $\mu $ is a nonnegative and exact Radon measure.
