    "abstract": "A simple quantum generalisation of the Liouville-Arnold criterion of\nclassical integrability is proposed: A system is quantum-integrable if it has\nan abelian Lie group of Wigner symmetries of dimension equal to the number of\ndegrees of freedom. The criterion goes significantly beyond the familiar case\nof involutive conserved operators to cover systems with anomalies in which\ninvolutivity is modified by central charges. \"Anomalous\" quantum integrability\nis shown to have all the expected consequences including exact\ndiagonalisability. The approach throws new light on the origin of Weyl group\ninvariance.",
