Description

I will start by recalling a general result, obtained together with Victor Carmona (Leipzig), about "algebras over not too little disks". I will then illustrate this result in dimension 1, using a construction (of a discrete 1d TFT on the line with a point defect) from a work in progress that is joint with Maziar Farahzad (Toronto). I will finally explain how this construction in particular recovers the well-known quantization of linear coisotropic reduction.
