摘要: 讨论由Young函数生成的Orlicz空间$L_{\mathit\Phi}^{*}(0,\infty)$的性质, 并给出Orlicz空间$L_{\mathit\Phi}^{*}(0,\infty)$具有Hardy-Littlewood性质的充要条件, 然后借助加Jacobi权修正的K-泛函和加Jacobi权连续模及其等价性建立Gamma算子在Orlicz空间$L_{\mathit\Phi}^{*}(0,\infty)$ 中加权同时逼近的两种强逆不等式.
关键词: Orlicz空间Young函数Gamma算子K-泛函    
Abstract: The properties of Orlicz spaces $L_{\mathit\Phi}^{*}(0,\infty)$ corresponding to the Young function $\mathit\Phi(x)$ are discussed and the Hardy-Littlewood property of the Orlicz spaces $L_{\mathit\Phi}^{*}(0,\infty)$ is given. Then two kinds of strong converse inequalities of Jacobi weighted simultaneous approximation for Gamma operators are established by modified Jacobi weighted $K$-functional and Jacobi weighted modulus of smoothness in Orlicz spaces $L_{\mathit\Phi}^{*}(0,\infty)$.
Key words: Orlicz Space    Young function    Gamma operators    strong converse inequality
