About

David Jaz Myers is a mathematician and category theorist by trade with a PhD from Johns Hopkins. Generally, David aims to understand what it means to be a thing, what form our notions of things may take, and how these forms affect our thinking and practice. In particular, he aims to use (higher) category theory and categorical logic to build a practical foundation for general systems theory and conceptual, collaborative scientific modelling.

Liberating synthetic quasi-coherence from forcing

In this blog post, I’ll reformulate Ingo Blechschmidt’s “synthetic quasi-coherence” axiom — or more precisely his “general nullstellensatz” — as a lifting property inspired by Ivan Di Liberti’s work on coherent toposes and ultrastructures. This lifting property shows that synthetic…

Structure-aware version control via observational bridge types

In this post, we suggest a way to use observational bridge types (as in the Narya proof assistant) for structure aware version control.

Categorical systems theory

Categorical systems theory is the study of the design and analysis of systems using category theory. Category theory is a hopelessly abstract branch of pure mathematics, so abstract that even the other mathematicians refer to it as “abstract nonsense”. Why would anyone want to study such complex…

Enriched categories as dynamical systems

Often in applied category theory, we hear about how systems form categories — categories of systems. But what about when the systems are categories? In this lecture, we introduce the idea of enriched categories, taking the point of view that an enriched category is a sort of dynamical system.
