Abstract

In this paper, we initially study when an anti-linear Toeplitz operator is in the commutant of a composition operator. Primarily, we investigate weighted composition operators Wg,ψW_{g,\psi} commuting with complex symmetric weighted composition operators Wf,φW_{f,\varphi} on the Hardy space H2(D)H^2(\mathbb{D}). In particular, we give the descriptions of the symbols gg and ψ\psi such that the inducing weighted composition operator Wg,ψW_{g,\psi} commutes with the complex symmetric weighted composition operator Wf,φW_{f,\varphi} with the conjugation J\mathcal{J}. Furthermore, we subsequently demonstrate that these weighted composition operators are normal and complex symmetric in accordance with the properties of the fixed point of the associated symbol φ\varphi.
