******************************************************************** | | | THE INTERNATIONAL LINEAR ALGEBRA SOCIETY ( ILAS ) | | ------------------------------------------------------ | | | | E-mail Address: MAR23AA @ TECHNION (bitnet) | | | ==================================================================== 23 February 1989 ------------------------ ILAS-NET Message No. 42 ------------------------- CONTRIBUTED ANNOUNCEMENT: FROM: Hans Schneider, Editor in Chief, LAA SUBJECT: LAA Special Issue -------------------------------------------------- Special Issue on ITERATIONS IN LINEAR ALGEBRA AND IN APPLICATIONS Contributions are invited for a special issue of Linear Algebra and its Applications entitled " Iterations in Linear Algebra and Applications". In the years following World War II much of the interest in iterative methods was motivated by the numerical solution to partial differential equations. This was followed by a period in which the scope and applications of iterative methods was broadened to cover the eigenvalue and least squares problems through the introduction of such algorithms as the QR and the SVD. In recent years, there has been a revival of interest in iterative methods because the introduction of vector and parallel supercomputing and other digital technologies in science engineering encouraged modelling and solution of problems of a very large scale. The scope of the issue includes the areas mentioned in the above short account. We give further examples below of topics which we would like to be addressed in the issue. Our list is by no means exhaustive and we welcome all other topics which are relevant to the title: i) Iterative methods for solving large linear systems, for example systems which arise in Multiple Coupled 3D PDE's. ii) Iterative methods for solving nonsymmetric systems and singular systems. iii) Sequential and parallel iterative algorithms for solving the eigenvalue and the least squares problems including applications to signal processing. Incomplete orthogonal factorization preconditioners. iv) Methods for determining subdominant eigenvalues of matrices. v) New approaches to implementing classical methods such as the SOR and SSOR together with appropriate analysis of convergence rate. vi) Preconditioned conjugate gradient methods. To what extent do efficient preconditioners depend on different type of computer architecture? vii) Substructuring and domain decomposition methods: their parallelization and their application in structural analysis and fluid flow. viii) Acceleration of iteration by techniques from approximation theory and analysis, for example, semi-iterative methods and Euler summation techniques. ix) Efficient implementation of iterative methods (such as multisplitting) on multiprocessor machines with shared and/or local memory. x) Solving nonlinear problems by linearization processes. For example: global optimization and updating techniques. Papers should meet the usual publication standards of Linear Algebra and its Applications. The deadline for submission is March 1990 with expected publication about a year later. Papers may be sent to any of the special editors listed below.
