Аннотация: For a wide class of Cohen–Macaulay modules over the local ring of the plane curve singularity of type $T_{36}$ we describe explicitly the corresponding matrix factorizations. The calculations are based on the technique of matrix problems, in particular, representations of bunches of chains.

Ключевые слова: Cohen–Macaulay modules, matrix factorizations, bimodule problems, bunches of chains.
