Link to stream workshop: https://msri.zoom.us/j/226801541 ***Due to the COVID-19 virus outbreak, the 2020 Tensor categories and topological quantum field theories workshop will no longer be held onsite at MSRI, rather it will take place online from March 16-20 as scheduled*** The decision to move this workshop online is based on the available scientific data on COVID-19, and the strong advice from experts to avoid gatherings of large groups. Announcement: Workshop Moved Online   Download Official Notice of Change A formal Notice of Change letter is available here, which can be shared with your institution, funding agency, and others.     Workshop Description: The workshop will concern the latest developments in the mathematical study of quantum field theories. The focus will be on the interplay among topics such as higher category theory, as illustrated by the cobordism hypothesis, conformal field theory, tensor categories describing the quantum symmetries, and the relation to topological phases of matter.
