We study a stochastic model of urban growth generating spatial distributions of population densities at an intermediate mesoscopic scale. The model is based on the antagonist interplay between the two opposite abstract processes of aggregation (preferential attachment) and diffusion (urban sprawl). Introducing indicators to quantify precisely urban form, the model is first statistically validat...

In this paper we consider modeling of credit risk within the Libor market models. We extend the classical definition of the defaultfree forward Libor rate to defaultable bonds with credit ratings and develop the rating based Libor market model. As driving processes for the dynamics of the default-free and the pre-default term structure of Libor rates time-inhomogeneous Lévy processes are used. ...
