Abstract : This report introduces a new random structure generalizing matroids. These random independence systems allow us to develop general techniques for solving hard combinatorial optimization problems with random inputs.

We review definitions of random hyperbolic sets and introduce a characterization using random cones. Moreover we discuss problems connected with symbolic representations and the thermodynamic formalism for random hyperbolic systems both in discrete and continuous time cases.

This paper was given as a presentation at the Jahrestagung der DMV in Berlin, 1992. It provides an overview of the theory of random dynamical systems (RDS's), and covers in a very short, but precise way the state of the art in the following areas: 1. Metric, topological, and smooth dynamics, 2. RDS: concept, invariant measures, 3. Generation of RDS, 4.

In Chap. 3, we discussed the statistical properties of an N-particle system treated within the framework of classical mechanics. In this chapter, we will take the more fundamental point of view that the particles and their interactions have to be described quantum mechanically. In quantum mechanics, the state of a system has to be described by a vector

High system reliability can be achieved by redundancy and maintenance. The most typical model is a standard parallel system which consists of \(n\) identical units in parallel. It was originally shown that the system can operate for a specified mean time by either changing the replacement time or increasing the number of units [1, p. 65].

Abstract Spin models in weak random fields are good representations of a large number of impure compounds which undergo magnetic or structural transitions. From a theoretical point of view these systems exhibit frustration on a mesoscopic scale and take therefore an indermediate position between (spin) glasses and unfrustrated (diluted) disordered ...

We all have an intuitive idea of what the word random means, in the sense of something being ‘chosen at random’, like picking numbers out of a hat or ‘drawing straws’, It is the meaning and interpretation of the word ‘random’, however, that led to probability theory falling into disrepute late last Century.

The salient result that emerges from the analyses of polling systems in the previous chapter is the large impact of overhead—particularly at light loading. Because of overhead, performance deteriorates with the number of stations irrespective of the total traffic in the system. On the other hand, as the total traffic in the system increases, the impact
