Clear filtersDeGiorgi.moserRegPowerCutoffWitness_grad
Plain-language statement
The gradient of moserRegPowerCutoffWitness decomposes as η · (chain rule) + (product rule). This is the analogue of deGiorgiCutoffTestWitnessWeighted_grad from Chapter 05.

DeGiorgi.moserRegPowerCutoffWitness_norm_sq_le
Project documentation
Pointwise gradient norm bound for the regularized powered cutoff. Extracted as a standalone lemma to keep the surrounding proof context small.

DeGiorgi.moserRegTestPow_nonneg_of_nonneg
Plain-language statement
The moserRegTestPow is nonneg on nonneg inputs: since smoothClip(t) ≥ 0 for t ≥ 0, we have (ε + smoothClip(t))^{p-1} ≥ ε^{p-1}.
