   Format: MarkdownItexSince I wondered what they were, I started an entry [[Gorenstein ring spectrum]], which then needed [[Gorenstein ring]]. Not sure I'm much the wiser as to their importance. There should be a lot to say about related duality.

   Format: MarkdownItexThe interest lies in the fact that Gorenstein ring spectra tend to exhibit Gorenstein duality. The latter is effectively a version of [[Anderson duality]]. The examples of Gorenstein duality that John Greenlees and his students mentioned in the talks yesterday were developments of the two examples that the nLab presently lists at _[[Anderson duality]]_. Lennart Meier has a hand in many of the recent examples that were computed, such as [arXiv:1607.02332](https://arxiv.org/abs/1607.02332)

   Format: MarkdownItexOne would hope that there is a good reference reviewing the basics, but I am not sure if there is. John Greenlees in his talk kept mentioning the many previous talks he had given on the subject.
