• Towards an understanding of ramified extensions of structured ring spectra 

      Dundas, Bjørn Ian; Lindenstrauss, Ayelet; Richter, Birgit (Journal article; Peer reviewed, 2020)
      We propose topological Hochschild homology as a tool for measuring ramification of maps of structured ring spectra. We determine second order topological Hochschild homology of the p-local integers. For the tamely ramified ...
