Introduction to DAG seminar



I'm a postdoctoral fellow in mathematics, currently working at SPHERE in Paris 7/Diderot.

Current interests :

  • Sweedler theory and Bar-cobar constructions
  • Relative algebraic geometry
  • Goodwillie Calculus and infinity-topos theory

- More slides of our work with André Joyal on bar-cobar constructions.

- The first version of our work with André Joyal on bar-cobar constructions.

- Slides of André Joyal's talk at the AMS meeting (Boston 2012) on our work on bar-cobar constructions barcobarboston.pdf
