symmetric monoidal (∞,1)-category of spectra
There are two different meanings of phrase “matrix factorization” which are closely related
(typically canonical) matrix decompositions of matrices into products of matrices of specific kind, like Gauss decomposition, polar decomposition, QR decomposition, LU decomposition etc.
decomposition of an element of a ring, understood as a multiple of an identity matrix, as a product of matrices over that ring, in the sense of Eisenbud and followers.
This entry is dedicated to the latter as it concerns appearance of certain categories in mathematical physics.
Matrix factorizations were introduced by David Eisenbud, and they were originally studied in the context of commutative algebra.
Matrix factorizations arise in string theory as categories of D-branes for Landau-Ginzburg B-models. This was proposed by Kontsevich and elaborated in the paper of Kapustin-Li.
Matrix factorizations have also been used by Khovanov-Rozansky in knot theory math/0401268.
Matrix factorization categories are examples of Calabi-Yau categories, hence correspond to TCFTs by the Costello/Kontsevich/Hopkins-Lurie theorem. The Calabi-Yau structure is elucidated in recent work of Dyckerhoff-Murfet and Polishchuk-Vaintrob.
Dyckerhoff has proved that the Hochschild homology of the matrix factorizations category of an isolated singularity is the Jacobian ring of the singularity. See also the work of E. Segal and Caldararu-Tu. In light of the Costello/Kontsevich/Hopkins-Lurie theorem, this result has been anticipated for some time, as the closed state space of a Landau-Ginzburg B-model is the Jacobian ring.
There is also the Calabi-Yau/Landau-Ginzburg correspondence. In some cases, categories of matrix factorizations turn out to be equivalent to categories of coherent sheaves.
For general theory and properties of matrix factorizations, see work of Orlov. For example, matrix factorization categories are related to derived categories of singularities.
(Eisenbud 1980) A matrix factorization of an element in a commutative ring is an ordered pair of maps of free -modules such that and .
Note that if is a matrix factorization of , then annihilates . Often instead of the assumption that -modules are free, one assumes that they are finitely generated projective.
