Summary: This paper deals with matrix transformations that preserve the \((p, q)\)-convexity of sequences. The main result gives the necessary and sufficient conditions for a nonnegative infinite matrix \(A\) to preserve the \((p, q)\)-convexity of sequences. Further, we give examples of such matrices for different values of \(p\) and \(q\).
