I'm happy that my proposal for an introductory course on Homotopy Type Theory / Univalent Foundations at the European Summer School in Logic, Language and Information 2026 in Prague was accepted!

A great opportunity to make use of @egbertrijke's recently published book, @MartinEscardo's lecture notes (in Agda!) and @danielgratzer and @carloangiuli's book draft!

Links for the curious:
- Egbert's book: https://doi.org/10.1017/9781108933568 & https://arxiv.org/abs/2212.11082
- Martín's notes: https://cs.bham.ac.uk/~mhe/HoTT-UF-in-Agda-Lecture-Notes/index.html
- Daniel and Carlo's book draft: https://www.danielgratzer.com/papers/type-theory-book.pdf

The 2026 Netherlands Winter School on Logic and Verification will take place Tuesday 20-Friday 23 January, 2026 at University of Twente. The school provides classes for PhD/graduate students in theoretical computer science, with a focus on software verification, logic, and type theory. Strong master students, as well as researchers and practitioners, are equally welcome. Participants are expected to have a background in theoretical computer science, mathematics or a related discipline at a master’s level, and have basic familiarity with (functional) programming, semantics, and logic.

Please consider registering! If you're a PhD student registered with the IPA school it will (very likely) be possible to get the costs reimbursed, but anyone with their own funding is welcome too.

My paper "Continuous and algebraic domains in univalent foundations" with @MartinEscardo was accepted for publication by the Journal of Pure and Applied Algebra! 🎉
https://martinescardo.github.io/papers/continuous-algebraic-domains-in-uf.pdf

This paper has its origin in my very first paper with Martín (and my second paper overall) "Domain Theory in Constructive and Predicative Univalent Foundations" which appeared at Computer Science Logic (CSL) back in 2021.

Since then I wrote my PhD thesis on this topic (and worked on other things in type theory after) and the present paper is a revision of both the CLS'21 paper and my PhD thesis (which I completed in 2022).

Everything in the paper has been formalized and an HTML rendering of the Agda file that directly links the code to the paper can be found here: https://martinescardo.github.io/TypeTopology/DomainTheory.Continuous-and-algebraic-domains.html
