Charged boson stars revisited
José Damián López, Miguel Alcubierre
We consider again stationary solutions to the spherically symmetric Einstein--Maxwell--Klein--Gordon system, commonly known as ``charged boson stars'', originally studied by Jetzer…
Random Market Models with an H-Theorem
Ricardo Lopez-Ruiz, Elyas Shivanian, Jose-Luis Lopez
In this communication, some economic models given by functional mappings are addressed. These are models for random markets where agents trade by pairs and exchange their money in…
A Generalized Continuous Model for Random Markets
R. Lopez-Ruiz, E. Shivanian, S. Abbasbandy +1
A generalized continuous economic model is proposed for random markets. In this model, agents interact by pairs and exchange their money in a random way. A parameter controls the e…
Exponential wealth distribution in a random market. A rigorous explanation
Jose-Luis Lopez, Ricardo Lopez-Ruiz, Xavier Calbet
In simulations of some economic gas-like models, the asymptotic regime shows an exponential wealth distribution, independently of the initial wealth distribution given to the syste…
The Limit Cycles of Lienard Equations in the Strongly Non-Linear Regime
Jose-Luis Lopez, Ricardo Lopez-Ruiz
Lienard systems of the form , with f(x) an even function, are studied in the strongly nonlinear regime (). A method for obtaining the number,…
