加权$θ$ -不完全多能理论
Weighted $θ$-Incomplete Pluripotential Theory
摘要:
加权多能理论是一个迅速发展的领域; Callaghan \cite{Callaghan}最近在\cd中为$d>1$引入了$θ$ -不完全多项式。本文通过定义加权$θ$ -不完全多能理论将这两种理论结合起来。定义了加权$θ$ -不完全极值函数,并利用$θ$ -不完全多项式得到了一个Siciak-Zahariuta型等式.最后证明了极值函数可以用正交多项式恢复,并在\cite{BermanCn}的基础上证明了Bergman函数的强渐近性.
英文摘要:
Weighted pluripotential theory is a rapidly developing area; and Callaghan \cite{Callaghan} recently introduced $θ$-incomplete polynomials in \cd for $d>1$. In this paper we combine these two theories by defining weighted $θ$-incomplete pluripotential theory. We define weighted $θ$-incomplete extremal functions and obtain a Siciak-Zahariuta type equality in terms of $θ$-incomplete polynomials. Finally we prove that the extremal functions can be recovered using orthonormal polynomials and we demonstrate a result on strong asymptotics of Bergman functions in the spirit of \cite{BermanCn}.
