k-quasi-A(n) and k-quasi-∗-A(n) composition and weighted composition operators on L2(µ)

In this paper, we discuss the conditions under which composition operators and weighted composition operators become quasi-A(n) operators, quasi-∗-A(n) operators, k-quasi-A(n) operators and k-quasi-∗-A(n) operators in terms of the Radon–Nikodym derivative hn.
