The 19th International Conference on Domain Decomposition Methods will be held on August 17-22, 2009 (Arrival day is August 16, 2009) at Zhangjiajie of China. The local host of the conference is School of Mathematics and Computational Science of Xiangtan University and Hunan Key Laboratory for Computation and Simulation in Science and Engineering. Domain decomposition is an active, interdisciplinary research area concerned with the development, analysis, and implementation of coupling and decoupling strategies in mathematical and computational models of natural and engineered systems. Historically, it emerged from the analysis of partial differential equations, beginning with the work of Schwarz in 1870. Since the advent of hierarchical distributed memory computers, it has been motivated afresh by considerations of concurrency and locality in a wide variety of large-scale problems, continuous and discrete. The current series of international meetings began in Paris in 1987 and has settled into an 18-month cycle. Meetings have been hosted in Austria, China, France, Germany, Israel, Italy, Japan, Mexico, Norway, Russia, the UK and the USA (see DDM home page: www.ddm.org for more information). Contribution to the 19th international conference are encouraged in areas of numerical analysis, computer science, scientific and industrial applications, and software development. The conference includes plenary lectures by leading experts and promising young scientists, participant-initiated minisymposia, contributed talks, and posters. Invited Speakers Randolph E.
