We prove basic facts about reflexivity in derived categories over noetherian
schemes; and about related notions such as semidualizing complexes, invertible
complexes, and Gorenstein-perfect maps. Also, we study a notion of rigidity
with respect to semidualizing complexes, in particular, relative dualizing
complexes for Gorenstein-perfect maps. Our results include theorems of
Yekutieli and Zhang concerning rigid dualizing complexes on schemes. This work
is a continuation of part I, which dealt with commutative rings.Comment: 40 page
