We consider Schrodinger operators in l(2)(Z) whose potentials are given by the sum of an ergodic term and a random term of Anderson type. Under the assumption that the ergodic term is generated by a homeomorphism of a connected compact metric space and a continuous sampling function, we ...

The proposed algorithm suggested a distributed adaptation of transmission parameters, where the knowledge obtained from a network by users can be used in a distributed manner in the KDN architecture. As data traffic increases in mobile networks and fixed spectrum allocation of operators becomes a ...
We show the existence of a natural further decomposition of the singular continuous componentAscinto a direct sum of two self-adjoint operatorsand. The corresponding subspaces and spectra are called decaying and purely non-decaying singular subspaces and spectra. Similar decompositions are also shown ...
The fine spectrum of the Cesàro operator of order one on the sequence space ℓp has been studied by Gonzàlez [3], where 1<p<∞. Also, weighted mean matrices of operators on ℓp have been investigated by Cartlidge [4]. The spectrum of the Cesàro operator of order one on the ...
SpectrumVoIP goes to great lengths to ensure that all customers have properly registered 911 addresses in order to ensure that operators can determine a caller’s location quickly and accurately, especially in scenarios where the caller is unable to speak or is unsure of their precise address locat...
operators. We will use the two representations interchangeably and the same symbols for both the abstract quantum channels and their matrix representations. One can use some fidelity measures to assess the performance of the implemented noisy gate\(\widetilde{{{\mathcal{U}}}\), such as process ...
The cumulative process implies the consideration of the nodes on the path when finding the routing path for the connection request. Generally, the more the nodes on the path, the greater the cumulative sum. The path with the lower SE becomes the final path to establish a connection at a low...
In general n-dimensional spacetime, the symmetry algebra consists of the semi-direct sum of the conformal Killing vectors of a (𝑛−2)(n−2)-dimension sphere acting on the ideal of infinitesimal supertranslations [7,27]. Recently, the existence of unexplored degrees of freedom closely ...
