In this talk, we describe a categorical approach of Saito's theory of primitive forms using matrix factorizations. This naturally leads to a definition of G-equivariant Saito theory. In the case of an invertible polynomial W with a diagonal special linear symmetry group G, we show that there exists a canonical choice of categorical primitive form. Conjecturally, the resulting invariants is mirror dual to the genus zero part of the FJRW theory.
