Systematic derivation of boundary Lax pairs

We systematically derive the Lax pair formulation for both discrete and continuum integrable classical theories with consistent boundary conditions.

💡 Research Summary

The paper presents a unified and systematic method for constructing Lax pairs for integrable classical field theories and lattice models when non‑trivial boundary conditions are imposed. Starting from the well‑known zero‑curvature condition ∂ₜL−∂ₓM+
