We study Hamiltonians with singular spectra of Cantor type with a constant ratio of dissection. The decay properties of the states in such systems depend on the nature of the dissection rate that can be characterized in terms of the algebraic number

We present a new approach to the spectral analysis and prediction of such complex systems for which the time evolution is described by a semigroup of operators. This approach is based on an extended concept of time operator and can be interpreted as

We extend the concept of implementability of semigroups of evolution operators associated with dynamical systems to quantum case. We show that such an extension can be properly formulated in terms of Jordan morphisms and isometries on non-commutative

We propose a new approach to the problem of e0cient resources distribution in di1erent types of economic systems. We also propose to use entropy as an indicator of the e0ciency of resources distribution. Our approach is based on methods of statistica

The quantum interference properties of simple model systems of arrays of barriers are considered. We discuss the capabilities for realizing new nanodevices based on the constructive interference for coding and decoding signals.

We present new general methods to obtain spectral decompositions of dynamical systems in rigged Hilbert spaces and investigate the existence of resonances and the completeness of the associated eigenfunctions. The results are illustrated explicitly f

An internal time operator is introduced for exact systems being typical examples of chaos and explicitly constructed for the Renyi map. The complete family of eigenvectors (age eigenfunctions) is explicitly presented. We prove that the time operator

The singular continuous spectrum of the Liouville operator of quantum statistical physics is, in general, properly included in the difference of the spectral values of the singular continuous spectrum of the associated Hamiltonian. The absolutely con

We present, on a simple model of aone-dimensional crystal lattice, the consequences of theassumption that the phases in the action-anglerepresentation are random. We prove that this assumptionamounts to the introduction of a stochastic measurewhich c
