In the framework of the Science Week of the University of Cantabria (13-24 November 2023), the Faculty of Science hosted an outstanding exhibition and poster competition, in which several research groups actively participated. Among them, the Open STEAM group presented a sample of their work in the framework of the AuthOMath project through the poster: ‘Resolviendo ecuaciones lineales con STACK / Solving linear equations with STACK’. We are pleased to report that the corresponding poster was awarded with the second prize!
