What is known about the matrix factorization categories of singularities of type ADE? Any references on this would be greatly appreciated.


Background: For ADE singularities, see for example [this](http://www.mathematik.uni-kl.de/~zca/Reports_on_ca/29/paper_html/node10.html). For matrix factorizations, see for example [this](https://mathoverflow.net/questions/9733/matrix-factorizations-and-physics/).



Matrix factorization categories for ADE singularities
See: "Matrix Factorizations and Representations of Quivers II: type ADE case" (math/0511155) by Kajiura, Saito, and Takahashi for a recent account.
