Multiplicative block preconditioner for the time-harmonic Maxwell equations
the multiplicative block preconditioner presented in this paper, block diagonal preconditioner established in (Greif and Schotzau, 2007) and block triangular preconditioner proposed in (Cheng, Huang and Shen, 2009), and numerically obtain the optimal parameter. Numerical experiments further verify the accuracy and practicability of the multiplicative block preconditioner.
Disclaimer/Regarding indexing issue:
We have provided the online access of all issues and papers to the indexing agencies (as given on journal web site). It’s depend on indexing agencies when, how and what manner they can index or not. Hence, we like to inform that on the basis of earlier indexing, we can’t predict the today or future indexing policy of third party (i.e. indexing agencies) as they have right to discontinue any journal at any time without prior information to the journal. So, please neither sends any question nor expects any answer from us on the behalf of third party i.e. indexing agencies.Hence, we will not issue any certificate or letter for indexing issue. Our role is just to provide the online access to them. So we do properly this and one can visit indexing agencies website to get the authentic information. Also: DOI is paid service which provided by a third party. We never mentioned that we go for this for our any journal. However, journal have no objection if author go directly for this paid DOI service.
