Sharp Beckner's Inequalities for Axially Symmetric Functions on $\mathbb{S}^N$

What the math gives to ML

The paper supplies a sharp functional inequality linking a spherical logarithmic moment-generating term to the quadratic energy of a high-order conformally invariant operator. Its transferable asset is the combination of a spectral Sobolev penalty, an exponential normalization term, and a geometric center-of-mass constraint with an explicit nonnegativity guarantee. A practical adaptation is a regularizer for axially symmetric spherical logits or score fields, where the network output is expanded in Gegenbauer modes and high-frequency energy is penalized while controlling the log-partition of the field. This is most plausible for spherical classification, directional diffusion, or neural fields rather than generic Euclidean transformers.
