Title:Improved analysis of preconditioners for GMRes method
Seminar:CCMA PDEs and Numerical Methods Seminar Series
Speaker:Yicong Ma, Penn State
Abstract:
Preconditioned GMRes method is an important iterative solver in practice. In literature, field-of-values equivalent precondition has been rigorously analyzed. We improve the existing estimates of the block triangular preconditioners for saddle point problems by removing the scaling parameters which usually is difficult to choose in practice. Application of such analysis to MHD system is also discussed.
