Existence and uniqueness of solutions for a general nonlinear variational inequality
AbstractIn this paper, two existence and uniquenss theorems of solutions for a general nonlinear variational inequality under reflexive Banach space settings are proved
Condensation and Evaporation of Mutually Repelling Particles :Steady states and limit cycles
We study condensation and evaporation of particles which repel each other,
using a simple set of rules on a square lattice. Different results are obtained
for a mobile and an immobile surface layer.A two point limit cycle is observed
for high temperature and low pressure in both cases. Here the coverage
oscillates between a high and a low value without ever reaching a steady state.
The results for the immobile case depend in addition on the initial coverage.Comment: 8 pages, 3 figure
A selection and a fixed point theorem and an equilibrium point of an abstract economy
A selection theorem and a fixed point theorem are proved. The fixed point theorem
is then applied to prove the existence of an equilibrium point of an abstract economy
Equilibrium points of random generalized games
In this paper, the concepts of random maximal elements, random equilibria
and random generalized games are described. Secondly by measurable selection theorem, some
existence theorems of random maximal elements for
Lc-majorized correspondences are obtained.
Then we prove existence theorems of random equilibria for non-compact one-person random
games. Finally, a random equilibrium existence theorem for non-compact random generalized
games (resp., random abstract economics) in topological vector spaces and a random equilibrium
existence theorem of non-compact random games in locally convex topological vector spaces
in which the constraint mappings are lower semicontinuous with countable number of players
(resp., agents) are given. Our results are stochastic versions of corresponding results in the
recent literatures
Bifurcation for the solutions of equations involving set valued mappings
This paper is devoted to a generalization of the bifurcation theorem of
Karsnosel'skii and Rabinowitz to the set valued situation
Percolation in Models of Thin Film Depositions
We have studied the percolation behaviour of deposits for different
(2+1)-dimensional models of surface layer formation. The mixed model of
deposition was used, where particles were deposited selectively according to
the random (RD) and ballistic (BD) deposition rules. In the mixed one-component
models with deposition of only conducting particles, the mean height of the
percolation layer (measured in monolayers) grows continuously from 0.89832 for
the pure RD model to 2.605 for the pure RD model, but the percolation
transition belong to the same universality class, as in the 2- dimensional
random percolation problem. In two- component models with deposition of
conducting and isolating particles, the percolation layer height approaches
infinity as concentration of the isolating particles becomes higher than some
critical value. The crossover from 2d to 3d percolation was observed with
increase of the percolation layer height.Comment: 4 pages, 5 figure
