Abstract
The mode fluctuation distribution (MFD) of quartic oscillators coupled by q uartic perturbations is studied. Using diagonalization of truncated sparse matrix of its Hamiltonian, we obtain 2500-5000 eigenvalues without missing levels. Both in two- and three-dimensions the MFD is much more sensitive to the integrability than the chaoticity of systems.
