Scaling behavior in economics: II. Modeling of company growth
S. V. Buldyrev, L. A. N. Amaral, S. Havlin +5
In the preceding paper we presented empirical results describing the growth of publicly-traded United States manufacturing firms within the years 1974--1993. Our results suggest th…
Scaling behavior in economics: I. Empirical results for company growth
L. A. N. Amaral, S. V. Buldyrev, S. Havlin +5
We address the question of the growth of firm size. To this end, we analyze the Compustat data base comprising all publicly-traded United States manufacturing firms within the year…
The Pinning Paths of an Elastic Interface
Hernan A. Makse, Sergey Buldyrev, Heiko Leschhorn +1
We introduce a model describing the paths that pin an elastic interface moving in a disordered medium. We find that the scaling properties of these ``elastic pinning paths'' (EPP)…
Driven Interface Depinning in a Disordered Medium
Heiko Leschhorn, Thomas Nattermann, Semjon Stepanow +1
The dynamics of a driven interface in a medium with random pinning forces is analyzed. The interface undergoes a depinning transition where the order parameter is the interface vel…
Avalanches and Correlations in Driven Interface Depinning
Heiko Leschhorn, Lei-Han Tang
We study the critical behavior of a driven interface in a medium with random pinning forces by analyzing spatial and temporal correlations in a lattice model recently proposed by S…
Interface Depinning in a Disordered Medium - Numerical Results
Heiko Leschhorn
We propose a lattice model to study the dynamics of a driven interface in a medium with random pinning forces. For driving forces F smaller than a threshold force F_c the whole int…
