Isolated hypersurface singularities as noncommutative spaces -- Tobias Dyckerhoff, November 20, 2009

Eisenbud's category MF of matrix factorizations is a differential graded category associated to the local germ X of a algebraic hypersurface. If the hypersurface is regular, then this category is trivial which, in general, allows us to think of MF as an invariant of the singularity of X. Noncommutative geometry based on dg categories allows us to interpret MF as the category of sheaves on a noncommutative space. We will explain how to obtain various properties (smoothness, properness) and invariants (de Rham cohomology, Hodge cohomology) of this space.
