Delta-extremal functions in Cn
Nurbek Kh. Narzillaev National University of Uzbekistan, Tashkent, Uzbekistan
Abstract:
The article is devoted to properties of a weighted Green function. We study the (δ,ψ)-extremal Green function V∗δ(z,K,ψ) defined by the class Lδ={u(z)∈psh(Cn): u(z)⩽Cu+δln+|z|, z∈Cn}, δ>0. We see that the notion of regularity of points with respect to different numbers δ differ from each other. Nevertheless, we prove that if a compact set K⊂Cn is regular, then δ-extremal function is continuous in the whole space Cn.
Keywords:
plurisubharmonic function, Green function, weighted Green function, δ-extremal function.
