Learning in the Transverse Subspace: A Minimal Representation for Divergence-Free Operator Learning
Yifei Sun
Divergence-free vector fields are fundamental state variables in incompressible flows and many PDE systems. Redundant parameterizations, including Neural Conservation Law (NCL) pot…

Solver-Integrated Adversarial Attacking and Training of Neural Operators
Yifei Sun
Neural operators are widely used as fast surrogates for numerical PDE solvers, mapping input functions to solution functions. However, their generalizability and robustness are not…
