We will talk about graded matrix factorizations for Calabi-Yau hypersurfaces in projective space. Using this description, the Jacobian algebra of the hypersurface naturally embeds into a ring of derived natural transformations of powers of a certain auto-equivalence on the derived category of coherent sheaves of the Calabi-Yau hypersurface. Taking a specific graded piece reproduces the classical result of Griffiths.
