Speaker: Weiguang Cao (IPMU, Tokyo University) Abstract: Recently, the notion of symmetry has been generalized. While ordinary symmetry can be described by a (1) co-dimension 1, (2) topological operator with (3) group-like fusion rule, generalized symmetries are described by operators that relax one or more conditions. Generalized symmetry plays an important role not only in …
Speaker: Ye Yuan (Zhejiang University) Abstract: In this talk I will discuss a differential representation for holographic four-point correlators. In this representation, the correlators are given by acting differential operators on certain seed functions. The number of these functions is much smaller than what is normally seen in known examples of holographic correlators, and all …
Speaker: Junwu Tu (ShanghaiTech University) Abstract: We shall discuss the categorical enumerative invariants associated with a smooth projective family of Calabi-Yau 3-folds. In particular, we study the holomorphic anomaly equations in this context. This naturally leads to the study of geometric structures on moduli spaces of smooth projective Calabi-Yau 3-folds. Time: 16:00 ~ 17:00, Mon., Mar. 25, 2024 …
Speaker: Satoshi Nawata (Fudan University) Abstract: The study of 3d mirror symmetry has greatly enhanced our understanding of various aspects of 3d N=4 theories. In this talk, starting with known mirror pairs of 3d N=4 quiver gauge theories and gauging discrete subgroups of the flavour or topological symmetry, I discuss new mirror pairs with non-trivial …
Speaker: Xinan Zhou (Kavli ITS, UCAS & ShanghaiTech University) Abstract: In this talk, I will discuss correlation functions in 6d (2, 0) theories of two 1/2-BPS operators inserted away from a 1/2-BPS surface defect. In the large central charge limit the leading connected contribution corresponds to sums of tree-level Witten diagram in AdS7×S4 in the …
