NON-PERTURBATIVE APPROACH TO RANDOM WALK IN MARKOVIAN ENVIRONMENT
Random Walk Random environment CLT Gibbs
2015/9/29
The study of random walk in random evolving environment has attracted much attention lately.
The basic idea is that, due to the time mixing properties of the environment, the CLT should hold
in any ...
Local Limit Theorems for Random Walks in a 1D Random Environment
RWRE quenched random environments
2015/9/29
We consider random walks (RW) in a one-dimensional i.i.d.
random environment with jumps to the nearest neighbours. For almost
all environments, we prove a quenched Local Limit Theorem (LLT) for
the...
QUENCHED LIMIT THEOREMS FOR NEAREST NEIGHBOUR RANDOM WALKS IN 1D RANDOM ENVIRONMENT
NEIGHBOUR RANDOM WALKS IMIT THEOREMS
2015/9/29
It is well known that random walks in one dimensional random environment can exhibit subdiffusive behavior due
to presence of traps. In this paper we show that the passage times
of diffe...
Linear free flexural vibration of cracked functionally graded plates in thermal environment
Functionally graded plate linear free vibration aspect ratio temperature gradient index crack finite element method
2011/9/15
Abstract: In this paper, the linear free flexural vibrations of functionally graded material plates with a through center crack is studied using an 8-noded shear flexible element. The material propert...
Branching diffusions in random environment
Branching process random environment diffusion approximation Laplace transform survival probability backbone construction
2011/9/6
Abstract: We consider the diffusion approximation of branching processes in random environment (BPREs). This diffusion approximation is similar to and mathematically more tractable than BPREs. We obta...
Annealed and quenched fluctuations for ballistic random walks in random environment on Z
Random walk in random environment stable laws
2011/1/19
We consider transient random walks in random environment on Z in the positive speed
(ballistic) and critical zero speed regimes. A classical result of Kesten, Kozlov and Spitzer proves that the hitti...
Optimization of air lift operation under fuzzy environment
Transportation Problem Triangular Fuzzy Numbers α − Optimal Solution
2010/11/1
The intention of this paper is to illustrate a diligence of fuzzy transportation model in airlift process contrived according to the atmospheric conditions throughout rainy seasons. This paper formula...
Supply chain model for the retailer's ordering policy under two levels of delay payments in fuzzy environment
Fuzzy numbers Function Principle
2010/9/21
In this paper we discuss the retailer’s ordering policy under two levels of delay payments by considering the selling price per item to be higher than the purchasing cost per item. The demand and sell...
Sensitivity analysis in fuzzy environment
Data envelopment Analysis Sensitivity analysis fuzzy data
2010/9/25
Data envelopment analysis (DEA) is a method to estimate the relative efficiency of decision-making units ( DMUs) performing similar tasks in a production system that consumes multiple inputs to produc...
We survey recent results and open questions on the ballistic phase of stretched polymers in both annealed and quenched random environments
We consider the effect of Gaussian white noise on fast-slow dynamical systems with one fast and two slow variables, containing a folded-node singularity. In the absence of noise, these systems are kn...

We continue our study of the parabolic Anderson equation $\partial u/\partial t = \kappa\Delta u + \gamma\xi u$ for the space-time field $u\colon\,\Z^d\times [0,\infty)\to\R$, where $\kappa \in [0,\in...

We consider a supercritical branching process $(Z_n)$ in a random environment $\xi$. Let $W$ be the limit of the normalized population size $W_n=Z_n/E[Z_n|\xi]$. We first show a necessary and sufficie...
