What

Independent research on transformer internals and the mathematical structures they implicitly compute on.

Typed Embeddings

Tokens don't just relate pairwise. Language has clauses with structure of their own, and the embedding space should know it — that's an algebra question, not a feature-engineering one. Active work.

The Harmonic Maass Form Framework

Different teams build different transformers — Mistral, Qwen, Pythia — and they converge on the same internal shape. The framework is one way of saying why: what they're all approximating belongs to a specific kind of mathematical object. Structural predictions hold cross-model.

Shadow-Line Helical Transformer (Transformer²)

Softmax is soft — it never actually chooses, it just biases the average. The architecture replaces it with hard structure that still moves: two interlinked helices in a curved space, where the geometry says where you are without forcing a choice.
