Researchers have developed a method to approximate Lyapunov functions for nonlinear dynamical systems using Fourier Neural Operators (FNOs). This approach aims to overcome the challenge of finding Lyapunov functions, which are crucial for stability analysis but are typically system-specific. The study establishes theoretical foundations for the Lyapunov solution operator, demonstrating its well-defined nature and continuity under certain stability assumptions. Numerical experiments show that a single trained FNO can accurately approximate Lyapunov functions across parameterized families of dynamics, highlighting the potential of neural operators in this field.
