| Abstract: | In algebraic geometry, we study varieties. These are spaces defined by algebraic equations. Three special kinds of varieties form the basic building blocks in algebraic geometry: they are the Fano varieties ("positive" case), canonically polarized varieties ("negative" case) and Calabi-Yau varieties ("neutral" case). We focus on the Calabi-Yau (or "neutral") case. Due to its "neutrality", its derived category has a self-dual structure. This motivates one to study these self-dual structures in general, which turns out to be a rich subject, with examples coming from topology, symplectic geometry, representation theory, etc. Moreover, Calabi-Yau categories are closely related to topological field theories. |
