Equivariant matrix factorizations
When we define equivariant matrix factorizations, P_1 and P_0 may have distinct group actions. For instance, if Z_3 acts on the complex line, then the action on the function ring(namely, C[z]) is naturally induced. Then let w=z^n, and think of the matrix factorization of w. Then P_1 and P_0 are both C[z] which are free C[z]=modules. To have nontrivial objects, we need to give different actions on each "module", not just taking a priori defined action on C[z].
