Deflation Methods in Fermion Inverters
Walter Wilcox
I will review recent developments in matrix deflation methods, by Ronald Morgan/Walter Wilcox, Andreas Stathopoulos/Konstantinos Orginos, and Martin Lüscher, with application to la…
Vacuum Expectation Values of Twisted Mass Fermion Operators
Abdou Abdel-Rehim, Randy Lewis, Walter Wilcox
Using noise methods on a quenched lattice at , we have investigated vacuum expectation values and relative linear correlations among the various Wilson and…
Magnetic Moment of Vector Mesons in the Background Field Method
Frank X. Lee, Scott Moerschbacher, Walter Wilcox
We report some results for the magnetic moments of vector mesons extracted from mass shifts in the presence of static external magnetic fields. The calculations are done on …
Deflated BiCGStab for linear equations in QCD problems
Abdou Abdel-Rehim, Ronald B. Morgan, Walter Wilcox
The large systems of complex linear equations that are generated in QCD problems often have multiple right-hand sides (for multiple sources) and multiple shifts (for multiple masse…
Deflated Iterative Methods for Linear Equations with Multiple Right-Hand Sides
Ronald B. Morgan, Walter Wilcox
A new approach is discussed for solving large nonsymmetric systems of linear equations with multiple right-hand sides. The first system is solved with a deflated GMRES method that…
Deflated GMRES for Systems with Multiple Shifts and Multiple Right-Hand Sides
Dean Darnell, Ronald B. Morgan, Walter Wilcox
We consider solution of multiply shifted systems of nonsymmetric linear equations, possibly also with multiple right-hand sides. First, for a single right-hand side, the matrix is…
