The n-groups are designed to generalize notions of connection and parallel tr ansport\, from curves to manifolds of dimension higher than one. They also give rise to a class of topological actions called nBF actions. One can t hen employ a 3-group as a gauge symmetry and the corresponding 3BF action\ , to describe the full Einstein-Cartan theory of gravity coupled to Standa rd Model fields. Such an action is naturally adapted to the spinfoam quant ization technique\, with the aim to construct a full model of quantum grav ity with matter.\n\nOnce constructed\, the properties of the model open up the possibility of a nontrivial unification of all fields. A 3-group natu rally contains additional novel gauge groups which specify the spectrum of fermions and scalars present in the theory\, just like the ordinary gauge group specifies the spectrum of gauge bosons in the Yang-Mills theory. Th e presence and the properties of new gauge groups have the potential to ex plain fermion families\, and other structure in the matter spectrum of the Standard Model.\n\nThe speaker is visiting Lisbon\, so local participants are invited to attend the talk in person in Room 3.10 (3rd floor Mathemat ics Department).\n LOCATION:https://researchseminars.org/talk/TQFT/69/ END:VEVENT END:VCALENDAR
