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...

LOCAL FORMULAS HYDRODYNAMIC PRESSURE APPLICATIONS
2014/4/3
We provide local formulas for the pressure of incompressible uids. The pressure can be expressed in terms of its average and averages of squares of velocity increments in arbitrary small neighborhoods...

2012/8/8
We consider H(curl; ?-elliptic variational problems on bounded Lipschitz polyhedra
and their 痭ite element Galerkin discretization by means of lowest order edge elements. We assume
that the underlyin...
Local Uniqueness of the Circular Integral Invariant
Integral invariants curves curve descriptors
2011/9/16
Abstract: This article is concerned with the representation of curves by means of integral invariants. In contrast to the classical differential invariants they have the advantage of being less sensit...

2012/11/30
Given a set of sensor nodes V where each node wants to broadcast a message to all its neighbors that are within a certain broadcasting range, the local broadcasting problem is to schedule all these re...

2011/2/28
We derive an upper bound for the mean of the supremum of the empirical process indexed by a class of functions that are known to have variance bounded by a small constant . The bound is expressed in ...

Lov´asz Local Lemma (LLL) is a probabilistic tool that allows us to prove the existence of combinatorial objects in the cases when standard probabilistic argument does not work (there are many p...
Based on two-grid discretizations, in this paper, some new local and
parallel finite element algorithms are proposed and analyzed for the
stationary incompressible Navier-Stokes problem.
These algo...
