A function , is a vectorial s-plateaued function if for each component function and , the Walsh transform value is either 0 or . In this paper, we explore the relation between (vectorial) s-plateaued functions and partial geometric difference sets. Moreover, we establish the link between three-valued cross-correlation of p-ary sequences and vectorial s-plateaued functions. Using this link, we provide a partition of into partial geometric difference sets. Conversely, using a partition of into partial geometric difference sets, we construct ternary plateaued functions . We also give a characterization of p-ary plateaued functions in terms of special matrices which enables us to give the link between such functions and second-order derivatives using a different approach.
