We shall be concerned only with the fluctuations of energy level positions

Measuring Inequality and Social Welfare motion have been rather well settled. As will probably appear in this Conference, the tentative definitions of quantum chaos are still sparse and conjectural, reflecting our poor understanding of the question. Our purpose here is to propose signatures of quantum chaos by means of statistical proper

https://doi.org/10.1007/0-387-33318-5system, no two of the energy levels E. will coincide. But just as with road accidents the chance of a degeneracy can rise from negligible to inevitable if instead of considering individual Hamiltonians one embeds Ĥ in a population smoothly parameterised by variables .. In section 2 I review an old a

Welfare and Inequality Dominanceates <n(E)> for a system with bound motion. Can it supply more refined ‘averages’ such as the correlation function for the density of states <n(E)n(E+ΔE)>? I shall argue that for the two extreme cases of integrable classical motion and ergodic classical motion information can indeed be obtained on n
