Pole-Tuned Graph Residual Layer

Use the graph Laplacian spectrum to set the mixing and correction coefficients of a two-state graph-propagation block. Balancing the contraction of low-frequency consensus modes against high-frequency disagreement modes may reduce oversmoothing and make deep graph-neural networks less sensitive to manually selected residual coefficients.

Commutator-Polynomial Residual Adapter

Replace an unconstrained linear residual adapter by an operator \(T\) satisfying a polynomial relation in the commutator operator \(\Delta_A(X)=AX-XA\). Choose the polynomial roots in a stable half-plane so that repeated commutators become nilpotent, making repeated adapter application terminate algebraically and permitting a finite-polynomial inverse of \(I+T\).

Semicircle-Calibrated Additive Initialization

Calibrate the scales of several additive self-adjoint residual or attention operators so their aggregate spectrum has a controlled higher-moment Berry–Esseen certificate. Penalize unusually large normalized (2+δ)-moments, which should reduce spectral outliers and make the summed operator closer to a predictable semicircle-shaped spectrum.

Polynomial Jacobian Non-Collapse

Add a two-output anti-collapse regularizer based on the determinant of the Jacobian Gram matrix, together with a penalty against proportional highest-degree coefficient tensors. The paper's inequality predicts that preserving coefficient non-proportionality prevents the output distribution from concentrating on thin curves or tiny regions, potentially improving coverage of a two-dimensional latent or generative output.

Expected Euler Interface Regularizer

For a neural scalar field defined on the vertices of a mesh or graph, generate several random level interfaces by adding continuous perturbations and thresholding the field. Penalize the deviation between the empirical mean Euler characteristic of these interfaces and the value predicted from the host complex's f-vector, encouraging decision boundaries with stable global topology.

Centro-affine spherical smoothness regularizer

Add a centro-affine Dirichlet penalty to a neural module whose inputs or outputs lie on a sphere, such as normalized embeddings or attention directions. The penalty measures intrinsic variation under an unconditional convex-body metric while projecting out the constant and coordinate-affine modes excluded by the theorem.

Reflection-Equation Expert Reset

Add a structured boundary-like operation to an MoE router that rapidly mixes expert probabilities toward a learned distribution while preserving predefined expert groups. The operation is a rank-one stochastic kernel, so it costs linear rather than quadratic work in the number of experts and can act as a controlled reset when routing becomes concentrated.

Adaptive Hankel constraint curriculum

Exploit the paper's nested obstruction hierarchy by applying cheap low-order Hankel tests to every example and evaluating larger matrices only for outputs near the current feasibility boundary. This turns higher-order structural validation into an adaptive curriculum rather than an always-on expensive eigendecomposition.

Hardy barrier for lattice feature fields

Treat a spatial feature map or lattice-indexed embedding as a function on a d-dimensional discrete grid and penalize excessive concentration near a chosen anchor using the inverse-radial Hardy weight. Calibrate the penalty with the theorem's high-dimensional scaling 2^ell d^ell instead of selecting an arbitrary spatial L2 coefficient.

Coherent-Fluctuating Amplitude Units

Represent selected hidden features as z = sqrt(N) exp(i theta), with a persistent phase and an explicitly stochastic amplitude. Regularize the ratio between coherent power |E[z]|^2 and total power E[|z|^2] toward the condensate prediction pi/4, while optionally matching higher amplitude moments.

Higher-Order Coactivation Envelope

Convert an attention or MoE routing affinity matrix into a soft graph and constrain its K_r-density relative to its observed K_s-density. The regularizer penalizes pathological affinity patterns in which moderate s-way coactivation is accompanied by an implausibly low or unstable r-way coactivation.

Distribution-Preserving Fragmentation Augmentation

Augment spatial training examples by replacing a compact active region with several separated components while preserving its exact value histogram, total active area, and amplitude. The augmentation probes the nonlinear interaction between diffusion-like receptive fields and threshold activations, which the paper shows can make fragmented and compact inputs evolve in opposite directions despite identical distributions.

Narayana-stable polynomial layer

Replace a monomial polynomial feature block by a fixed Narayana basis transformation. If the input polynomial has nonnegative coefficients and only real roots, the transformed polynomial is guaranteed to have only real roots as well, giving a certified stability-preserving coordinate change for polynomial neural networks.

Reaction-Closed Sparse Routing

Represent the active experts or channels of a sparse layer by a presence set and impose a reaction-style dependency graph on possible support changes. During a growth phase, activate only the least support set closed under enabled dependencies; during later pruning, allow trajectory-dependent removals but never add structurally unreachable experts. This should reduce routing churn and dead experts while preserving adaptive sparsity.
