Lifting (co)stratifications between tensor triangulated categories
英文摘要：
We give necessary and sufficient conditions for stratification and costratification to descend along a coproduct preserving, tensor-exact $R$-linear functor between $R$-linear tensor-triangulated categories which are rigidly-compactly generated by their tensor units. We then apply these results to non-positive commutative DG-rings and connective ring spectra. In particular, this gives a support-theoretic classification of (co)localizing subcategories, and thick subcategories of compact objects of the derived category of a non-positive commutative DG-ring with finite amplitude, and provides a formal justification for the principle that the space associated to an eventually coconnective derived scheme is its underlying classical scheme. For a non-positive commutative DG-ring $A$, we also investigate whether certain finiteness conditions in $\mathsf{D}(A)$ (for example, proxy-smallness) can be reduced to questions in the better understood category $\mathsf{D}(H^0A)$.
