Perfectoid Rings Breakdance in Sonic Pi?

May 25, 2026·sketch notes

I move through perfectoid rings, p-adic towers, and the Frobenius map, wondering if any of it could ever end up in Sonic Pi’s sandbox.

Do Group Actions Define Regular Polytopes and Polytypes in Type Systems?

Do Group Actions Define Regular Polytopes and Polytypes in Type Systems?

I introduce an analogy between transitive group actions on flags of polytopes and type systems. This speculative concept aims to offer a naive way of understanding and classifying types through symmetry.

Gamma Functions for Figurate Numbers

Gamma Functions for Figurate Numbers

I plant a question motivated by generalizing the GCD to varieties and inspired by Euler's interpolation: Does there exist a function attached to each figurate number that extends it to continuous domains, analogous to how the Gamma function extends the factorial?

Counting a Figurate Property in Cayley–Dickson Algebras

Dec 27, 2025·sketch notes

A naive question about Cayley-Dickson algebras, enumerated by a figurate number via type systems, and how that question naturally incorporates itself into other algebraic structures and particularities.

Category of Modules and Type-Level Programming with Figurate Numbers

Category of Modules and Type-Level Programming with Figurate Numbers

I invite you to explore the intersection of figurate numbers and module theory, where type-level programming unlocks new possibilities for math and live coding music.
