Abstract: | We construct an invariant of t-structures on the derived category of a commutative noetherian ring. This invariant is complete when restricting to the category of complexes with finitely generated bounded homology, and also gives a classification of nullity classes with the same restriction. On the full derived category of Z we show that the class of distinct t-structures do not form a set. |
