Title: Derived Morita equivalence


Abstract:  Two rings are called Morita equivalent if their categories of modules are equivalent. We will review Morita's classic theorem providing a criterion for when that happens. We will then consider the question: When do two rings have equivalent derived categories? Rickard's theorem provides an answer. Lastly, we will look at the derived category of a DG-algebra and tackle the question: When do two DG-algebras have equivalent derived categories?
