DESCRIPTION:Leandre Portela: Abstract :\n\nSymmetries play a fundamental ro le in physics\, providing powerful tools to understand the fundamental law s of the universe. In this seminar\, we will explore the fascinating conce pt of asymptotic symmetries\, which describe the properties of space-time at infinity\, revealing infinite-dimensional symmetry algebras. We will fi rst review some basic concepts of general relativity. Then\, we will exami ne the case of asymptotically flat spacetimes\, where the symmetry algebra is the infinite-dimensional Bondi-Metzner-Sachs (BMS) algebra.\n\nThe mai n objective of this talk is to provide an overview of the concept of asymp totic symmetries\, which has numerous applications and is frequently discu ssed in seminars in the field of gravitation.\n \;\n\n\n\nLe séminai re des doctorant⋅es de l’I2M et du CPT à Luminy regroupe chaque sema ine les doctorant⋅es du site autour d’un exposé plus ou moins (in)for mel\, dans un cadre convivial. Il est évidemment ouvert aux étudiant⋅e s de master et aux doctorant⋅es d’autres laboratoires.\n\nPour le mome nt\, le séminaire a lieu dans la salle 500-504b du TPR2\, au 5ème étage .
