The Spectrum and The Numerical Range of W_f,φ W_f,ψ* and W_f,ψ* W_f,φ
Abstract
In this paper we study the spectrum and the numerical range of weighted composition operator with the adjoint of weighted composition operator W_f,φ W_f,ψ* and W_f,ψ* W_f,φ induced by linear –fractional self- maps 𝜑 𝑎𝑛𝑑 𝜓 of 𝕌 on Hardy space ℍ2.
