   Format: MarkdownItexI have added pointer to * [[Yves Diers]], _Une construction universelle des spectres, topologies spectrales et faisceaux structuraux_, Communication in Algebra Volume 12, Issue 17-18 (1984) ([doi:10.1080/00927878408823101](https://doi.org/10.1080/00927878408823101)) * {#Osmond2020a} [[Axel Osmond]], _On Diers theory of Spectrum I: Stable functors and right multi-adjoints_, ([arXiv:2012.00853](https://arxiv.org/abs/2012.00853)) * {#Osmond2020b} [[Axel Osmond]], _On Diers theory of Spectrum II: Geometries and dualities_, ([arXiv:2012.02167](https://arxiv.org/abs/2012.02167)) but I haven't read these and can't vouch for these, just adding them because there was already * [[Axel Osmond]], _The general construction of Spectra_ ([arXiv:2102.01259](https://arxiv.org/abs/2102.01259)) and it seemed that if we mention Osmond 21 we need to mention Diers 84, of which it claims to be an exegesis. But before all these I have added pointer to * [[Monique Hakim]], _Topos annel&#233;s et sch&#233;mas relatifs_, Ergebnisse der Mathematik und ihrer Grenzgebiete, Band 64, Springer, Berlin, New York (1972) ([doi:10.1007/978-3-662-59155-0](https://www.springer.com/gp/book/9783540055730)) * [[Jacob Lurie]], _[[Structured Spaces]]_ which I _can_ vouch for :-) Also cross-linked with our entry _[[Cole's theory of spectrum]]_. <a href="https://ncatlab.org/nlab/revision/diff/spectrum+%28geometry%29/9">diff</a>, <a href="https://ncatlab.org/nlab/revision/spectrum+%28geometry%29/9">v9</a>, <a href="https://ncatlab.org/nlab/show/spectrum+%28geometry%29">current</a>

   but I haven’t read these and can’t vouch for these, just adding them because there was already

   • Axel Osmond, The general construction of Spectra (arXiv:2102.01259)

   and it seemed that if we mention Osmond 21 we need to mention Diers 84, of which it claims to be an exegesis.

   • Jacob Lurie, Structured Spaces

   which I can vouch for :-)

   Also cross-linked with our entry Cole’s theory of spectrum.

   Format: MarkdownItexOh, I see now that Dmitri was the one who added pointer to Osmond's article in [#1](#Comment_89480). Dmitri, maybe if you could add a line on the idea of Diers-Osmond? (I haven't had the leisure yet to read their articles).

   Format: MarkdownItexOkay! I mentioned the Diers spectrum in the list of spectra. I also created a separate article [[Diers spectrum]]. <a href="https://ncatlab.org/nlab/revision/diff/spectrum+%28geometry%29/10">diff</a>, <a href="https://ncatlab.org/nlab/revision/spectrum+%28geometry%29/10">v10</a>, <a href="https://ncatlab.org/nlab/show/spectrum+%28geometry%29">current</a>
