Venue

The Mathematics Department (DMat-UA) was founded in 1976 immediately after the foundation of the University of Aveiro.
In a university campus full of harmony, a true gallery of modern Portuguese architecture, we can envisage the building which hosts the Mathematics Department since 1993. Designed by the architect José Prata and displaying elegant lines, this building has a magnificent glass dome, providing light into its interior. It is part of one of the most dynamic an innovating Portuguese universities and employs a team of highly experienced and qualified professors.
