I will then showcase simple but surprising examples in 4d and 6d wher e ordinary and 1-form global symmetries are necessarily fused together int o a higher structure known as a 2-group. Time permitting\, I will discuss some applications to superconformal theories in 6d.\n\nZoom Meeting ID: 92 4 6768 3111\nPassword: 620110\n(You will enter a waiting room for a brief period.)\n LOCATION:https://researchseminars.org/talk/USC-HET/1/ END:VEVENT END:VCALENDAR
