We present the results of a 2D and 3D electrical conductivity simulation of a metal-insulator composite in the range of cluster plasmon frequencies. For the 3D simulations we use an extension of the matrix transfer method that was first introduced to calculate the percolation critical exponents...

The loss angle δ is used to characterize the dielectric properties of inhomogeneous materials, in the framework of percolation theory. We have shown that δ takes the universal value δ = πs/2(s + t) at the percolation threshold (p = pc), and low frequency (ε → 0), where s and t are the...

We report experimental results on the flicker noise in a fractal lattice. The exponent b value is found equal to 1. We give preliminary results on the behaviour of a square lattice made up of resistors whose values are distributed with a R−α probability.

We define a new strategic equilibrium concept -called strong collusion- proof contract -designed to characterize stable communication agreements in games with differential information against non-binding, self enforcing and incentive compatible deviations by coalitions.We then construct a...

In this paper, we prove an existence theorem for equilibria in production economies with increasing returns, which generalizes the classis results on this topic. In partular, we eliminate both the free-disposal assumptions and any smoothness requirements on the boundary of the production sets....

We present a feasible strategic market mechanism with .nitely many agents whose Nash, semi-strong Nash and coalition-proof Nash equilibria fully im plement the Walrasian equilibria. We define a strategic equilibrium conce pt, called correlated semi-strong equilibrium,and show that the Walrasian...

L'objectif de ce papier est, en premier lieu, d'analyser la dynamique induite par des chocs fiscaux dans un modele d'equilibre general intertemporel stochastique dans lequel l'hypothese d'equivalence ricardienne n'est pas verifiee (l'horizon des agents etant plus court que celui du...
