| Heisenberg Vertex Algebra | Myself: An introduction to vertex algebras, with the Heisenberg algebra as an example. The operator product expansion and some mild geometric intutition is also covered. |

| The sheaf of chiral differential operators | Ryan Grady |
| CDO's and the Witten Genus | Nick Rozenblyum |
| Supersymmetric field theories in dimension 2 | Si Li |
| Perturbative observables of the (0,2) theories | Yuan Shen |
| The chiral de Rham complex, orbifolds, and the half-twisted sigma model | Matt Szczesny |
