An example concerning Sadullaev’s boundary relative extremal functions

Jan Wiegerinck Annales Polonici Mathematici MSC: 32U05, 32U20. DOI: 10.4064/ap180604-19-6 Published online: 9 July 2018


We exhibit a smoothly bounded domain $\Omega $ with the property that for suitable $K\subset \partial \Omega $ and $z\in \Omega $ the Sadullaev boundary relative extremal functions satisfy $\omega _1(z,K,\Omega )<\omega _2(z,K,\Omega )\le \omega (z,K,\Omega )$.
