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.

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.

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.
