Regularity of Mean-Field Games : an introduction
(2020-08-18)
Mean-field games, introduzido numa perspectiva de equações diferenciais parciais por Lions e Lasry, modelam situações com um grande número de agentes considerado um contínuo. O estudo da regularidade de funções é observar ...
Convergence to the Mean Field Game Limit: A Case Study
(Inst Mathematical Statistics, 2020)
We study the convergence of Nash equilibria in a game of optimal stopping. If the associated mean field game has a unique equilibrium, any sequence of n-player equilibria converges to it as n -> infinity. However, both the ...
Mean-field approach to diffusion with interaction: Darken equation and numerical validation
(American Physical Society, 2018-08-22)
A mean-field theory for diffusion with interaction was introduced in Phys. Rev. E 92, 062118 (2015)PLEEE81539-375510.1103/PhysRevE.92.062118. Interaction effects are represented with a mean-field potential. Here we show ...
From diffusion experiments to mean-field theory simulations and back
(IOP Publishing, 2019-11)
Using previous experimental data of diffusion in metallic alloys, we obtain real values for an interpolation parameter introduced in a mean-field theory for diffusion with interaction. Values of order one were found as ...
Pseudospin and spin symmetries in the relativistic harmonic oscillator
(2006-12-01)
We compute the analytical solutions of the generalized relativistic harmonic oscillator in 1+1 dimensions, including a linear pseudoscalar potential and quadratic scalar and vector potentials which have equal or opposite ...

On a correlation between the ionospheric electric field and the time derivative of the magnetic field
(Hindawi, 2012-02-20)
A correlation of the ionospheric electric field and the time derivative of the magnetic field was noticed over thirty years ago and has yet to be explained. Here we report on another set of examples during the superstorm ...
Far-field angular distribution of the mean scattered intensity from strong diffusers by means of a near-field intensity pattern
(Optical Society of America, 2010-04-01)
The speckle grain close to a diffuser medium carries information about the angles at which light is scattered. We propose the extension of a technique that allows obtaining the angular distribution of the scattered intensity ...
Invasion and extinction in the mean field approximation for a spatial host-pathogen model
