DESCRIPTION:Thematic 3-weeks programme at the Institut Henri Poincaré\, 
 Paris\, June 15th to July 3rd\, 2026.\nBeware: It was reported to us that 
 scammers are sending to participants fraudulent e-mails about accomodation
 /fees. Please be particularly cautious about e-mails not coming from the o
 rganisers nor from an @ihp.fr address. \nAbstract\nSome of the most profo
 und open problems about the physics of quantum fields – especially at st
 rong coupling\, beyond the reach of conventional techniques – are newly 
 accessible thanks to recent developments in topological quantum field theo
 ry (TQFT). This insight comes with a dramatic evolution of the notion of s
 ymmetries in QFT: symmetries can be characterized via topological defects 
 of various codimensions whose multidimensional fusion generalizes wildly t
 he notion of groups to what are called categorical symmetries. This IHP pr
 ogram is the fourth in a series of meetings hosted at various institutes w
 orldwide devoted to the exploration of these aspects of symmetries\, the 
 resulting mathematical structures and their physical implications\, in the
  context of the Simons Collaboration on Global Categorical Symmetries. Wor
 ld-class experts in the subject will gather at IHP in an interactive setti
 ng alternating lectures and seminars aiming at nourishing collaborations a
 nd stimulate further this rapidly evolving field.\nDuring the first week o
 f this program we invite PhD students and postdocs to the fourth GCS summe
 r school. Support is available for those who apply. During the second week
  of this program we will host the conference Symmetries 2026\, an interna
 tional gathering of experts where the most recent developments about this 
 topic will be presented. The third week of this program is a smaller works
 hop\, where groups of researchers are welcome to network and develop new p
 rojects and ideas. More information will appear on this webpage closer to 
 the event.\n \nThe program unfolds over three weeks: a school\, a confere
 nce\, and finally a workshop.\nJune 15-19: GCS26 School\nIHP\, Amphithéâ
