Abstract
Given a family \( \{ A_m^x \} _{\mathop {m \in \mathbb{Z}_ + ^d }\limits_{x \in X} } \) (X is a non-empty set) of bounded linear operators between the complex inner product space \( \mathcal{D} \) and the complex Hilbert space ℌ we characterize the existence of completely hyperexpansive d-tuples T = (T 1, … , T d ) on ℌ such that A xm = T m A x0 for all m ∊ ℤ d+ and x ∊ X.
