This mini course on homotopy theory, derived categories and hermitian forms aims to gather specialists in these areas and to foster interaction, especially between confirmed and young researchers. This event is organized by the Algebra and Geometry team of the Laboratoire de Mathématiques de Lens, and is supported by the Fédération de Recherche Mathématique des Hauts-de-France, the Université d'Artois in the framework of the BQR support (Bonus Qualité Recherche), and the Réseau Thématique 2171 of CNRS "Topologie Algébrique et Géométrique".

The program includes three 5-hours courses, and a few short talks.

Courses:

Paul Balmer (University of California at Los Angeles): Tensor-triangular geometry of permutation modules.

Yonatan Harpaz (Institut de Mathématiques de Jussieu): Trace methods for hermitian K-theory.

Thomas Unger (University College Dublin): Real algebraic aspects of algebras with involution



Short talks: The short talks will be announced later.
