This is the private area of David Roberts within the nLab.

I am a postdoctoral research fellow at the University of Adelaide in South Australia.

For my papers (including PhD thesis) please see here. This site is to gather teaching material, but also more ephemeral things.

Notes

  • Theorem A for topological categories - this is a version of Quillenā€™s Theorem A for categories in TopTop. As a corollary, with a condition on the unit map of the codomain we get that geometric realisation of an š¯’©\mathcal{N}-equivalence is a homotopy equivalence.

  • Serreā€™s proof of the Grothendieck-Serre theorem on the Brauer group of a compact space. (to be uploaded).

Mathematical publishing

I have views about the current system of academic publishing, especially how it impacts mathematics. Two links of interest:
