Abstract: The concept of gauge origami refers to a system of intersecting branes in string theory that realizes multiple supersymmetric gauge theories living on intersecting subspaces. In this talk, I will discuss the BPS counting of the D6–D2–D0 gauge origami system from the viewpoint of a 3d–1d coupled system. This BPS counting is related to the equivariant Pandharipande–Thomas (PT) 3-vertex, whose appropriate limit reproduces the (refined) topological vertex. I will also discuss how the DT/PT correspondence naturally emerges from supersymmetric quantum mechanics associated with this brane configuration. This talk is based on an on-going work with Jiaqun Jiang, Taro Kimura, Go Noshita, Jiahao Zheng.
About Speaker: Satoshi Nawata is a Professor at Fudan University. He earned his PhD in 2008 from the University of Wisconsin, Milwaukee, under the supervision of Luis Alfredo Anchordoqui. Prior to joining Fudan, he held postdoctoral positions at Wisconsin U., Tata Institute, Perimeter Institute, Nikhef (Amsterdam), Warsaw University, and Caltech. His area of research comprises mathematical physics, quantum field theory, and string theory.
