Error analysis of the Lie splitting for semilinear wave equations with finite-energy solutions
First error analysis for Lie splitting on Ḣ¹ solutions of energy-critical semilinear wave equations on R³ yields order-1 L² convergence and order-3/2 for the corrected scheme via discrete Strichartz estimates with frequency cutoffs.
