Partitioning the vertex set of $G$ to make $G\,\Box\, H$ an efficient open domination graph

open access: yes, 2016
A graph is an efficient open domination graph if there exists a subset of vertices whose open neighborhoods partition its vertex set. We characterize those graphs $G$ for which the Cartesian product $G \Box H$ is an efficient open domination graph when ...

Polyharmonic functions of infinite order on annular regions [PDF]

open access: yes, 2012
Polyharmonic functions f of infinite order and type {\tau} on annular regions are systematically studied. The first main result states that the Fourier-Laplace coefficients f_{k,l}(r) of a polyharmonic function f of infinite order and type 0 can be ...

Models of Type Theory Based on Moore Paths

open access: yes, 2019
This paper introduces a new family of models of intensional Martin-L\"of type theory. We use constructive ordered algebra in toposes. Identity types in the models are given by a notion of Moore path.

Assembling the Proofs of Ordered Model Transformations

open access: yes, 2013
In model-driven development, an ordered model transformation is a nested set of transformations between source and target classes, in which each transformation is governed by its own pre and post- conditions, but structurally dependent on its parent ...

Control of Four-Level Quantum Coherence via Discrete Spectral Shaping of an Optical Frequency Comb

open access: yes, 2008
We present an experiment demonstrating high-resolution coherent control of a four-level atomic system in a closed (diamond) type configuration. A femtosecond frequency comb is used to establish phase coherence between a pair of two-photon transitions in ...

Comparison of dynamics of neurological disorders regression in postoperative period in patients with subaxial cervical spine injury depending on constructive fusion system type

open access: yesUkrainian Neurosurgical Journal, 2018
Introduction. Two types of constructive solutions for fusion of subaxial cervical spine traumatic injury are possible. The first is an independent combination of interbody implant and anterior plating, the second one is the single telescopic ...

Chebyshev-Type Quadrature Formulas for New Weight Classes

open access: yes, 2011
We give Chebyshev-type quadrature formulas for certain new weight classes. These formulas are of highest possible degree when the number of nodes is a power of 2. We also describe the nodes in a constructive way, which is important for applications.
