Regularize a spatiotemporal neural model with spectral penalties corresponding to several temporal-spatial scaling laws rather than using a single isotropic smoothness penalty. The model can remain spatially detailed while suppressing temporal oscillations, or learn the opposite preference when the data demand it.

Constrain a positive asymmetric recurrent or state-space transition operator by penalizing its principal eigenvalue through local ratio evaluations rather than repeated eigendecomposition. Introduce a periodic logarithmic corrector whose optimized local quotients provide a differentiable, conservative estimate of the operator's growth rate; this is especially suitable for sparse nearest-neighbor transitions.

Augment a hidden representation with positively homogeneous interaction features built from approximate eigenmodes of a linear layer. Fractional products of mode magnitudes and phases provide nonlinear channels whose transformation laws are inherited from the spectrum of the underlying operator, potentially representing oscillatory or multiplicative dynamics more compactly than a generic MLP.

Normalize every higher-order simplicial message-passing or diffusion block using the spectral radius of a lower-order up-Laplacian, rather than estimating a separate radius for each order. The paper's monotonicity theorem guarantees that this shared bound is conservative for all higher orders, enabling stable explicit updates with one spectral calibration.

Represent a feature field with positive channel amplitudes and penalize violations of the paper's system-wide relative-variation bound. Unlike per-channel total variation, the penalty constrains only aggregate channel mass, allowing channels to exchange mass through signed or non-cooperative mixing while keeping the overall representation stable. The method is most natural for intermediate CNN maps, positive SSM states, or sequence embeddings indexed by a coordinate with meaningful local…

Construct a branching residual network whose active computational paths reproduce according to a fixed offspring/connectivity law, while a controller can only remove paths using an age- or depth-dependent hazard \(u(a)\). Use the resulting bound as a diagnostic and gating schedule: removal can suppress unstable activity and reduce compute, but it should not be expected to cross the reproduction-driven propagation barrier unless the network's expansion operator is also changed.

Replace unconstrained recurrent-state decay with a one-dimensional latent defect field whose states evolve by local diffusion and pair reactions. Defects can move over long distances and persist, while creation and removal occur only in pairs, giving the memory a structured cancellation mechanism that is potentially better suited to delayed-event and parity-like sequence dependencies than a standard GRU or diagonal SSM.

Replace the linear state transition in a recurrent layer with a bank of odd-power modified Emden oscillators. The nonlinear terms provide state-dependent interactions while the paper's odd-q result preserves period T=2π/ω independently of amplitude, giving the model a stable internal phase clock for long sequences. External inputs should modulate the oscillator through a bounded forcing or readout gate rather than directly destroying the autonomous isochronous dynamics.

Apply a weak-trace spectral constraint to the covariance of antisymmetric second-order features, encouraging a 1/i eigenvalue envelope rather than forcing a finite trace norm. This targets the paper's sharp logarithmic Ky Fan behavior and may preserve useful long-tail interaction directions that nuclear-norm regularization would remove.

Replace a learned causal mixing profile by a monotone profile followed by a prefix-average Hardy mixer. The monotonicity constraint makes the mixer provably non-degenerate in the BMO sense: localized variation in the profile cannot be reduced below a calibrated factor by prefix averaging. This is a cheap alternative to dense causal attention for tasks where importance or state profiles are expected to decay along sequence position.

Add a trajectory-level loss that matches the empirical distribution of consecutive velocity turning angles between observed and generated sequences. Because turning angles are unchanged by a common rotation of all coordinates, the model is forced to reproduce hidden anisotropic and temporally correlated motion without being given a fixed laboratory-frame orientation.

Initialize and train a linear recurrent or state-space transition using the stochastic Lyapunov operator rather than only constraining the drift matrix to be Hurwitz. Start from a controller that stabilizes the drift-only dynamics, then continuously increase the multiplicative-noise coefficient and update the controller while enforcing a positive-definite Lyapunov certificate. The resulting module should avoid exploding hidden states when process noise depends on the hidden state or input.

Equip a latent transition model with a near-identity polynomial coordinate transform that conjugates the nonlinear transition to a linear latent operator, at least locally around a reference state. Train the transform jointly with the dynamics using both the usual prediction loss and the paper's splitting/intertwining residual, so that multi-step prediction is performed partly in approximately linearised coordinates.

Replace a dense channel-mixing matrix in a sequence layer with alternating diagonal propagation and sparse unipotent Stokes jumps. The diagonal part carries independently controlled exponential phases, while the unipotent factors implement cheap residual-like mode conversion without changing determinant or requiring a dense matrix multiply.

Add an algebraic diversity barrier to a companion or polynomial state-space layer so that its coordinate projections do not become simultaneously degenerate.

Replace a uniformly discretized recurrent or continuous-depth model with hybrid hidden-state dynamics: integrate a learned drift between event times, then apply a one-sided reflection update at each irregular observation or constraint event. The reflection prevents the hidden state from violating a lower obstacle, while the explicit jump decomposition avoids smearing abrupt information changes across many small residual steps.

Train Fourier or state-space neural models by eliminating well-conditioned spectral modes first and retaining near-resonant modes until a later stage. The schedule is determined by the small-divisor geometry of a reference transport vector, with a cumulative Brjuno-like budget controlling how aggressively spectral corrections may be applied. This should prevent rare nearly resonant modes from producing disproportionately large gradients or unstable long-horizon rollouts.
