Classifying dg-categories of matrix factorizations
Martin Kalck
We give a complete classification of differential -graded homotopy categories of matrix factorizations of isolated singularities up to quasi-equivalence. This answers a…

A new equivalence between singularity categories of commutative algebras
Martin Kalck
We construct a triangle equivalence between the singularity categories of two isolated cyclic quotient singularities of Krull dimensions two and three, respectively. This is the fi…
