Parent event:

Seminar on Algebra, Geometry and Physics We will discuss categorical construction of the moduli spaces of curves and various compactifications.

This involves the operations of push-forward of functors or Kan extensions and W-constructions in the

framework of Feynman categories. We also show that there is a tower of compactifications that

is naturally available though the master equation and canonical blow-downs. This is joint work with

Clemens Berger and Javier Zuniga.
