    "abstract": "The dynamics of a quantum system undergoing frequent measurements (quantum\nZeno effect) is investigated. Using asymptotic analysis, the system is found to\nevolve unitarily in a proper subspace of the total Hilbert space. For spatial\nprojections, the generator of the \"Zeno dynamics\" is the Hamiltonian with\nDirichlet boundary conditions.",
