Aug 4, 2022 at 12:09 comment added Igor Khavkine Does this answer your question? Reference request: Systems of linear PDES with constant coefficients
Aug 4, 2022 at 6:22 comment added asv @IgorKhavkine : Apparently the references there are what I need. Thanks a lot.
Aug 3, 2022 at 19:34 comment added Igor Khavkine The exactness of your composition $D_2 \circ D_1=0$ in polynomials is essentially "formal exactness". Exactness in smooth functions is called "strict exactness" (in reference to this function class). For constant coefficient operators formal exactness implies strict exactness. Is your question essentially a duplicate of this earlier question? See my answer there for a reference to a detailed discussion.
