In recent years the rapid development of telecommunication networks, typically for cellular phones or the internet, has required much more sophisticated tools to ensure the proper flow of messages. Many of these tools have an important mathematical component, and several areas of mathematics have contributed to the field. New challenges are coming up. To be met, they will require to set up further collaborative ventures that the Forum hopes to put in the proper light.
