Computer Algebra refers to the study and design of algorithms for manipulating mathematical expressions and objects. It is naturally at the interface between Mathematics, Computer Science, and various application fields. It covers a wide range of subjects, such as effective linear algebra, algorithmic number theory, integration and summations in closed-form expression, differential and polynomial system solving, or special functions. The French Computer Algebra community takes part in the organization of the main international conferences (ISSAC, FoCM, MEGA, . . . ). On top of scientific excellence in their theoretical works, members of this community also develop for widely used software such as Maple, SageMath and Magma, and software libraries such as mpfr, pari, fgb, rs, linbox, etc. The vitality of this community is also recognized by prestigious national prizes (e.g. CNRS medal). This success is notably due to the Journées Nationales de Calcul Formel (JNCF), which is a remarkable opportunity for researchers to discuss recent and ongoing work with their peers. Expected outcomes include:

A better integration of young researchers. The JNCF are an ideal opportunity for young researchers to present their results for the first time and also to get an overview of the various advances in Computer Algebra. This is especially important in the Computer Algebra community, where researchers need to build skills in both Computer Science and Mathematics. New collaborations and interactions. The JNCF have traditionally been an opportunity to create successful collaborations between researchers from different parts of France. The JNCF has also opened to an international community, while remaining primarily French-speaking. The previous editions already included courses and contributed talks by colleagues from other European and Mediterranean countries.
