The competition of user networks: Ergodicity, lock-ins, and metastability

Woeckener, Bernd W. - 1998

This paper models the competition of user networks as a continuous-time Markov process. It presents a dynamic version of the Discrete Choice Analysis with state-dependent choice probabilities. Among other things, we show that the network competition can be characterized by the coexistence of...

Large deviations, metastability and selection

Kurchan, Jorge - In: Physica A: Statistical Mechanics and its Applications 418 (2015) C, pp. 170-188

In this note I introduce some techniques to treat systems in contact with (stochastic) thermal baths. The methods and the level of rigour are those of theoretical physics.

Speed of convergence for laws of rare events and escape rates

Freitas, Ana Cristina Moreira; Freitas, Jorge Milhazes; … - In: Stochastic Processes and their Applications 125 (2015) 4, pp. 1653-1687

We obtain error terms on the rate of convergence to Extreme Value Laws, and to the asymptotic Hitting Time Statistics, for a general class of weakly dependent stochastic processes. The dependence of the error terms on the ‘time’ and ‘length’ scales is very explicit. Specialising to data...

Spike pinning for the Gierer–Meinhardt model

Iron, David; Ward, Michael J. - In: Mathematics and Computers in Simulation (MATCOM) 55 (2001) 4, pp. 419-431

The pinning effect induced by two different types of spatial inhomogeneities on the dynamics and equilibria of a one-spike solution to the one-dimensional Gierer–Meinhardt (GM) activator–inhibitor model of morphogenesis is studied. The first problem that is treated is the shadow problem that...

Approach to equilibrium of the hydrogen atom at low temperatures

Oliveira-Neto, N.M.; Curado, E.M.F.; Nobre, F.D.; … - In: Physica A: Statistical Mechanics and its Applications 374 (2007) 1, pp. 251-262

The dynamics of the approach to equilibrium of the hydrogen atom is investigated numerically through a Monte Carlo procedure. We show that, before approaching ionization, the hydrogen atom may live in a quasi-equilibrium state, characterized by aging, whose duration increases exponentially as...
