On Difference Operators and their Factorization
Canadian Journal of Mathematics, 1983Throughout this paper A will be used to denote a given set and g a permutation of it. We shall assume that there is a subset C ⊆ A so that1Here Z denotes the set of integers. For x ∈ A it now follows that there is an unique α(x) ∈ Z so that2and then alsoIn general we shall be concerned with solving the following equation for u3where pi, n ≤ i ≤ r, and ...

Difference sets and inverting the difference operator
Combinatorica, 1996For \(A\subseteq N_0\) let \(D(A)\) be the set of differences of elements of \(A\) in \(N_0\). Problem: study equations \(D^k(X)=B\). There is a solution if \(0\in B\) and for each \(n\) there exists \(x\geq n\) such that each of the \(2^{k-1}\) intervals \([x-n, x+n]\), \([2x-n, 2x+n],\dots,[2^{k-1}x-n, 2^{k-1}x+n]\) is contained in \(B\).

Homogenization of Elliptic Difference Operators
SIAM Journal on Mathematical Analysis, 2001We develop some aspects of general homogenization theory for second order elliptic difference operators and consider several models of homogenization problems for random discrete elliptic operators with rapidly oscillating coefficients. More precisely, we study the asymptotic behavior of effective coefficients for a family of random difference schemes ...

Comment on ‘‘Phase-difference operator’’
Physical Review A, 1995We examine the operator \ensuremath{\Phi}${\mathrm{^}}_{12}$ proposed by Luis and S\'anchez-Soto [Phys. Rev. A 48, 4702 (1993)] as a possible description of the phase difference between two electromagnetic fields. We show that there is a difficulty in directly representing the phase difference between arbitrary fields by this operator, but conclude ...

Deadlocks in Different Operating Systems
2015 12th International Conference on Information Technology - New Generations, 2015The world has evolved so quickly in the field of information and technology, especially in those parts that include computer engineering. Operating systems are a very big proof that demonstrates this evolution. We were very interested in the treatment of this theme starting from the curiosity on how deadlocks perform in different OS, especially in ...

Operator-Difference Scheme with a Factorized Operator
2015In the study of difference schemes for time-dependent problems of mathematical physics, the general theory of stability (well-posedness) for operator-difference schemes is in common use. At the present time, the exact (matching necessary and sufficient) conditions for stability are obtained for a wide class of two- and three-level difference schemes ...
