The retrieved literature supports the premise that integrable systems are characterized by extensive conservation laws enabling analytical tractability, whereas breaking these invariants transitions systems into chaotic behavior.
Papers [0], [2], [4], [5], and [7] all explicitly link the presence of conservation laws and complete integrability to analytical tractability (exact solutions) and contrast this with the lack of such invariants in chaotic or non-integrable systems. No papers refute the claim.
