摘要

Many authors have generalized Boolean functions with values over finite fields to functions valued over \(\mathbb {Z}_{p^k}\) . In this work, we generalize their main properties to functions with values in Galois rings. We mainly study relations between generalized bent functions and their classical component functions. A connection with affine spaces of classical bent functions is established.
