摘要

Consider a complex plane \({\mathbb {C}}\) C and open unit disk \({\mathbb {D}}= \{z\in {\mathbb {C}}:|z|<1\}\) D = { z C : | z | < 1 } . Let \(\phi _{1}\) ϕ 1 , \(\phi _{2}\) ϕ 2 be two holomorphic functions on \({\mathbb {D}}\) D , and let \(\xi\) ξ be a holomorphic self-map of \({\mathbb {D}}\) D . For \(n\in {\mathbb {N}}_{0}\) n N 0 , where \({\mathbb {N}}_{0}=\{0,1,2,\dots \}\) N 0 = { 0 , 1 , 2 , } , a new product type operator on \(H({\mathbb {D}})\) H ( D ) is defined by: \(\begin{aligned} T_{\phi _{1},\phi _{2},\xi }^{n}f(z)= \phi _{1}(z)f^{(n)}(\xi (z))+ \phi _{2}(z)f^{(n+1)}(\xi (z)), \;\;\; f\in H({\mathbb {D}}), \;z\in {\mathbb {D}}, \end{aligned}\) T ϕ 1 , ϕ 2 , ξ n f ( z ) = ϕ 1 ( z ) f ( n ) ( ξ ( z ) ) + ϕ 2 ( z ) f ( n + 1 ) ( ξ ( z ) ) , f H ( D ) , z D , where \(f^{(k)}\) f ( k ) denotes the kth derivative of the function f. In this paper, we investigate the boundedness and compactness of these type of operators acting between weighted Bergman–Orlicz spaces and some weighted-type spaces.
