Open 2D TFTs admit initial open-closed extensions

Shaul Barkan, Jan Steinebrunner, Adela YiYu Zhang

We show that any open 2-dimensional topological field theory valued in a symmetric monoidal $\infty$ -category (with suitable colimits) extends canonically to an open-closed field t…

2-dimensional TFTs via modular $\infty$ -operads

Jan Steinebrunner

This lecture series is based on joint work in progress with Shaul Barkan, as well as work in progress of the author. The five sections of these notes correspond to the five lecture…
