Abstract
<div class="line" id="line-19"> We show that a noetherian ring R is regular if and only if each complex of injective R-modules is semi-injective if and only if each acyclic complex of injective R-modules is contractible. Analogous results are established for complexes of flat modules and of projective modules.</div>
