Abstract
Let 𝔻 = {z ∈ C : |z| < 1} be the unit disk and Hol(𝔻 × 𝔻) be the space of all holomorphic functions on the bi-disc 𝔻 × 𝔻. We consider the double convolution operator 𝒦f on the subspace Holzw(𝔻 × 𝔻) := {f ∈ Hol(𝔻 × 𝔻) : f(z,w) = g(zw) for some g ∈ Hol(𝔻)} defined by
We study extended eigenvalues of 𝒦f . We characterize extended eigen vectors of 𝒦f in terms of Duhamel operators. Moreover, we describe cyclic vectors of operator 𝒦f by applying the Duhamel product method.
