From prlina at ipb.ac.rs Wed Jan 22 11:41:22 2025 From: prlina at ipb.ac.rs (prlina) Date: Wed, 22 Jan 2025 11:41:22 +0100 Subject: [phys4phys] Group for Gravitation, Particles and Fields seminar, Wednesday, 29 January 2025 Message-ID: Dear colleagues, You are cordially invited to the seminar of the Group for Gravitation, Particles and Fields, which will be held on Wednesday, 29 January 2025, at 13:00 at the University of Belgrade Faculty of Physics, lecture hall 665. Please note that the seminar location and time are different than usual. The talk entitled: Higher form symmetries of the M2-brane will be given by Mar?a Del Pilar Garc?a Del Moral Zabala (Science and Technology Faculty Universidad de La Rioja, Spain). Abstract: In this talk I will describe the existence of invertible Higher form symmetries on the M2-brane. I will explain the cancellation of the 't Hooft anomaly and how in the cases of compactified spaces this is related to the existence of a 1-Gerbe structure over the M2-brane that when projected on the spatial part of the worldvolume represents a flux condition. Interestingly, the major part of the sectors of the M2-brane that have been found with good quantum properties are associated to the imposition of a worldvolume flux condition. I will also comment briefly on the extension of these symmetries to the non-invertible case. ********************************************* Time: January 29, 2025 13:00 Belgrade University of Belgrade Faculty of Physics, room 665, 3rd floor ********************************************* Best regards, Igor Prlina
