Notes

  1. Domain theory and denotational semantics (March 2023).
    Lecture notes with exercises for an introductory course at the upcoming Midlands Graduate School at the University of Birmingham, UK.
  2. Constructive taboos involving trichotomous ordinals (April 2022).
    HTML rendering of an Agda formalization with comments.
  3. Semidecidability: constructive taboos, choice principles and closure properties (January 2022).
    HTML rendering of an Agda formalization with comments.
  4. Constructing the circle using propositional truncations and univalence (January 2021).
    HTML rendering of an Agda formalization with comments.
    This formalization largely follows the wonderful paper Construction of the circle in UniMath by Marc Bezem, Ulrik Buchholtz, Daniel R. Grayson and Michael Shulman, although we do not prove the induction principle directly (as is done in Section 4.2 of the paper), but rather derive it abstractly from the universal property of the circle.
