| Classification of Cones for Calabi-Yaus |
| Speaker: | Harald Skarke (TU Wien) |
| Abstract: | Calabi-Yau hypersurfaces in toric varieties can be described via reflexive polytopes. A generalized construction involving reflexive
Gorenstein cones affords descriptions of Calabi-Yau manifolds of higher
codimension as well as Landau-Ginzburg models. After reviewing some of the relevant concepts and the algorithm that led to the classification of reflexive polytopes in three and four dimensions, I will indicate how this algorithm needs to be be modified so that it can be applied to reflexive Gorenstein cones. I will also point out open classification problems that may well lie within the range of contemporary computer power. |

| The hemisphere partition function and Landau-Ginzburg orbifolds |
| Speaker: | Dr. Emanuel Scheidegger (Univ. Freiburg) |
| Abstract: | Starting with a variation of GIT quotients with potential we will review
how to associate a function on the K-theory of the resulting spaces,
called the hemisphere partition function. In case the resulting space is
a Landau-Ginzburg orbifold we will relate this function to natural
functions associated in the Landau-Ginzburg orbifold. |
