In most states with market oriented economic systems privatisation plays an important role in the political discussion, mainly due to the fundamental problem of all economic systems, which is scarcity of available resources. The responsible politicians try to improve the allocation of scarce...

Social segregation in cities takes place where different household groups exist and when, according to Schelling, their location choice either minimizes the number of differing households in their neighbourhood or maximizes their own group. In this contribution an evolutionary simulation based...

Usually in the monocentric city models, the spatial patterns of segregated ethnic groups are assumed to be ring-shaped, while early in the 1930ies, Homer Hoyt showed, that wedge-shaped areas predominate empirically. After Rose-Ackerman's discussion of the influence of aversion one group of...

Since EU members have agreed to establish integrated military forces and to decide jointly on their deployment in European institutions, the EU’s “democratic deficit†is no longer confined to issues of common market governance but also includes foreign, security and defense...

Stochastic particle methods for the numerical treatment of the Boltzmann equation for dilute monatomic gases are considered. One particular stochastic model of particles with weights is introduced. Recent convergence results for this model are discussed. The introduction of certain degrees of...

In this paper, we review recent results concerning stochastic models for coagulation processes and their relationship to deterministic equations. Open problems related to the gelation effect are discussed. Finally, we present some new conjectures based on numerical experiments performed with...
