The chapters in this contributed volume explore recent advances in applied and computational mathematics. Chapters are based on talks given at the "International Conference on Research in Applied Mathematics and Computer Science" held at Cadi Ayyad University, Morocco in April 2025. Papers cover a range of areas, including stochastic modeling, cryptographic systems, functional analysis, and more. Advances in Applied and Computational Mathematics will appeal to researchers and graduate students interested in learning more about the connections between theory and applications.
