Benefits from generalized diagonal dominance
نویسنده
چکیده
Generalized diagonal dominance, a specific property of the matrix, can be very useful in various fields of the applied linear algebra, as a tool for discovering and proving new results. First, it gives possibility to be able to define different subclasses of H-matrices (papers [3], [11]). Second, it suggests a way to deduce and prove new theorems on the eigenvalue localization (papers [2], [4], [5], [10], [14], [15]). Third, it gives the possibility to obtain new results on the convergence of iterative methods (papers [1], [6], [7]). Fourth, it is a tool for proving new properties of Schur complements (papers [8], [12]) and new features of the matrix sums (paper [9]). Finally, the generalized diagonal dominance was proven to be an indispensable tool in getting the first results on the localization of generalized eigenvalues (paper [13]).

OPM: a parallel method to solve banded systems of equations
studied in this report. We can see, in general, that low accuracies will require less overlapping and, in those cases, the algorithm will run faster. As the diagonal dominance increases, the amount of overlapping will be lower and the timings for different accuracies within the same diagonal dominance will get closer and closer. In this report we presented the Overlapped Partitions Method, a me...

We review the generalized vector dominance (GVD) approach to DIS at small values of the scaling variable, x. In particular, we concentrate on a recent formulation of GVD that explicitly incorporates the configuration of the γ * → q ¯ q transition and a QCD–inspired ansatz for the (q ¯ q)p scattering amplitude. The destructive interference, originally introduced in off-diagonal GVD is traced bac...
متن کاملLocalization of generalized eigenvalues by Cartesian ovals
In this paper, we consider the localization of generalized eigenvalues, and we discuss ways in which the Gersgorin set for generalized eigenvalues can be approximated. Earlier, Stewart proposed an approximation using a chordal metric. We will obtain here an improved approximation, and using the concept of generalized diagonal dominance, we prove that the new approximation has some of the basic ...
متن کاملEffective Mass Generation of Off-diagonal Gluons and Abelian Dominance in the Maximally Abelian Gauge in QCD
We study the properties of gluons in QCD in the maximally abelian (MA) gauge. In the MA gauge, the off-diagonal gluon behaves as the massive vector boson with the mass Moff ' 1.2 GeV, and therefore the off-diagonal gluon cannot carry the long-range interaction for r M−1 off ' 0.2 fm. The essence of the infrared abelian dominance in the MA gauge is physically explained with the generation of the...

We show the construction of the dual superconducting theory for the confinement mechanism from QCD in the maximally abelian (MA) gauge using the lattice QCDMonte Carlo simulation. We find that essence of infrared abelian dominance is naturally understood with the off-diagonal gluon mass moff ≃ 1.2GeV induced by the MA gauge fixing. In the MA gauge, the off-diagonal gluon amplitude is forced to ...
