This website from the California Institute of Technology (Caltech) features "the interwoven fields of applied and computational mathematics." Highlighting the interdisciplinary nature of the field, the group's work draws on modeling, analysis, algorithm development, and simulation to address problems arising in the pure sciences and engineering. Students and faculty explore the mathematical properties of systems in physics, chemistry, biology, geology, astronomy, materials science, fluid mechanics, and other disciplines. At the time of this report, the section offering Technical Reports was still under development. However, some of the individual researchers have links to websites (within the People section) with a list of publications, some of which are available to download free of charge. Abstracts of Colloquia at Caltech also provide the visitor an overview of topics that interest this group of researchers.
