Morita Theory For Derived Categories: A Bicategorical Perspective [PDF]
arXiv, 2008 We present a bicategorical perspective on derived Morita theory for rings, DG algebras, and spectra. This perspective draws a connection between Morita theory and the bicategorical Yoneda Lemma, yielding a conceptual unification of Morita theory in derived and bicategorical contexts.
