摘要:

在这项工作中,我们推广了Békollè-Bonami $B_p$权理论。这里我们用一个非负的可测函数$p(\cdot),$代替常数$p$,它是一个具有下界$1$的log-Hölder连续函数。我们证明了$\mathbb C^n$的单位球上的Bergman投影在加权变Lebesgue空间$L^{p(\cdot)}(w)$上是连续的当且仅当$w$属于广义Békollè-Bonami类$B_{p(\cdot)}$ .为了实现这一点,我们定义了一个极大函数,并表明它是有界的$L^{p(\cdot)}(w)$,如果$w\in B_{p(\cdot)}$。接下来我们陈述并证明一个加权外推定理,使我们能够得出结论。

英文摘要:

In this work, we extend the theory of Békollè-Bonami $B_p$ weights. Here we replace the constant $p$ by a non-negative measurable function $p(\cdot),$ which is log-Hölder continuous function with lower bound $1$. We show that the Bergman projector on the unit ball of $\mathbb C^n$ is continuous on the weighted variable Lebesgue spaces $L^{p(\cdot)}(w)$ if and only if $w$ belongs to the generalised Békollè-Bonami class $B_{p(\cdot)}$. To achieve this, we define a maximal function and show that it is bounded on $L^{p(\cdot)}(w)$ if $w\in B_{p(\cdot)}$. We next state and prove a weighted extrapolation theorem that allows us to conclude.
