Combinatorics, topology, and control

Advanced Geometry Gallery

This gallery is the conceptual map for the ToricGT training stack. It connects tropical dynamic programming, toric embeddings, tableau combinatorics, tensor operations, multiparameter persistence, intersection-style certificates, and control of reasoning trajectories. Every diagram is a lightweight inline SVG with accompanying text so the page stays readable on older hardware.

Tropical Ring Attention Embedded In A Toric Fan

Yᵢc = maxⱼ(Sᵢⱼ + Vⱼc)active affine candidate → Newton face → normal cone chart

Tropical attention is piecewise-linear. The active candidate set is a face of a lifted Newton polytope, and the corresponding normal cone is the toric chart used by the audits.

Training use: fan-margin, active-face stability, toric embedding metrics, and BPB-safe routing diagnostics.

Young Tableaux And Schur-Style Coordinates

Tableaux encode structured bases for polynomial and exterior constructions. They are useful when graph-token features behave like tensor products but need symmetry constraints.

Training use: candidate future losses for symmetrizer/shuffle consistency and combinatorial certificate compression.

Tensor, Wedge, Symmetric, And Shuffle Relations

V ⊗ W∧²V: v⊗w − w⊗vSym²V: v⊗w + w⊗vShuffle maps tell the model which feature products should commute, anticommute, or decompose.

Graph-token reasoning creates many pairwise and higher-order feature products. Algebraic symmetry gives a principled way to constrain which products should be identified or separated.

Training use: low-rank probes for wedge/symmetric consistency and future Schur-functor-inspired regularizers.

F₂[x_level,y_radius] Persistence Modules

reasoning levelradius

The full reasoning trajectory can be filtered by reasoning level and embedding radius. Algebraically, this is a two-parameter persistence module over F₂[x_level,y_radius].

Training use: GUDHI landscapes/images/entropy, simplex-map gates for analogical memory, and Macaulay2 resolution checks.

Thought Alcove Control

control u(t) keeps trajectories inside stable fan alcovesLyapunov, ergodic, and optimal-control diagnostics

Reasoning paths move through fan cells. A stable path should cross walls for reasons tied to the task, not because the latent state is noisy.

Training use: fan-margin scheduling, branch pruning, FoT reward shaping, and future control-theoretic audits.

Intersection And Divisor Certificates

σλσμintersection-style numbers become compact certificate features

Toric divisors, one-dimensional cones, and intersection numbers provide compact summaries of how a local piecewise-linear decision bends across walls.

Training use: toric vector-bundle one-dimensional-cone CE, sheaf compatibility, and divisor/fan audit metrics.
