Equations play a crucial role in modern mathematics and form the basis for mathematical modelling of numerous phenomena and processes in science and engineering. The international scientific-educational website EqWorld presents extensive information on solutions to various classes of ordinary differential, partial differential, integral, functional, and other mathematical equations. It also outlines some methods for solving equations, includes interesting articles, gives links to mathematical websites and software packages, lists useful handbooks and monographs, and refers to scientific publishers, journals, etc. The website includes a dynamic section Equation Archive which allows authors to quickly publish their equations (differential, integral, and other) and also exact solutions, first integrals, and transformations. The EqWorld website is intended for researchers, university teachers, engineers, and students all over the world. It contains about 2000 webpages a

Science-advisor.net is a free articles search engine and online forum for scientific discussions and short reviews. Search articles in Physics, Astrophysics, Mathematics, Biophysics, etc.

Le serveur TEL (thèses-en-ligne) a pour objectif de promouvoir l'auto-archivage en ligne des thèses de doctorat et habilitations à diriger des recherches (HDR), qui sont des documents importants pour la communication scientifique entre chercheurs.
