arXiv:2607.00320v1 Announce Type: cross Abstract: We establish approximation and learning guarantees for Fourier neural operators (FNOs) applied to time-$T$ solution operators of dissipative evolution equations. The analysis builds on the premise that FNOs can efficiently approximate and learn solution operators whenever these operators admit stable and accurate spectral discretizations. To formalize this idea, we introduce classes of evolution operators defined through spectral methods and derive FNO approximation bounds and polynomial sample complexity guarantees for these classes.

This research provides theoretical guarantees for Fourier neural operators' ability to approximate and learn complex physical systems, which is crucial for their application in scientific computing and real-world engineering. It addresses the fundamental question of reliability and predictability in advanced AI models, fostering trust for industrial adoption.
The established approximation and learning guarantees for FNOs reduce the uncertainty around their performance, enabling more confident application in areas requiring high accuracy and stability like climate modeling, drug discovery, and materials science. This moves FNOs from experimental tools to validated scientific instruments.
