This symmetry has an interesting property: it does not admit si mple (Lagrangian) formulations that manifest it. Furthermore\, it is seemi ngly broken in the real world by the presence of matter that has only elec tric charges. Thus\, both theoretical challenges and questionable practica l usefulness of this symmetry do not encourage the development of new form ulations that make use of it. However\, there are related theoretical mode ls that require such formulations. We will discuss a new formulation of el ectromagnetic field theory and its generalizations\, that combines the man ifest electric-magnetic duality symmetry with manifest space-time symmetri es.\n\ntalk host: Zhirayr Avetisyan (the language can be Armenian or Engli sh\, depending on the choice of the audience)\n LOCATION:https://researchseminars.org/talk/YMC/50/ END:VEVENT END:VCALENDAR
