Query: A somewhat gentle introduction to differential graded commutative
  algebra   Differential graded (DG) commutative algebra provides powerful techniques for
proving theorems about modules over commutative rings. These notes are a
somewhat colloquial introduction to these techniques. In order to provide some
motivation for commutative algebraists who are wondering about the benefits of
learning and using these techniques, we present them in the context of a recent
result of Nasseh and Sather-Wagstaff. These notes were used for the course
"Differential Graded Commutative Algebra" that was part of the Workshop on
Connections Between Algebra and Geometry held at the University of Regina, May
29--June 1, 2012.
