A repository of the Max Planck Institute for Mathematics in the Sciences in Leipzig, dedicated to mathematical research data, namely all digital objects that arise during the process of doing research or are a result thereof. It is open to contributions with some restrictions: publications are only possible for scientists of the MPI MiS and their collaborators.
Searchable database of “interesting” graphs, where here a graph is interesting if one of the (registered) users of the website decides so. It also aims to serve as a central repository for complete lists of graphs (which can be downloaded in several formats) of various graph classes and the generators that can be used to generate these graphs. Registered users can add new graphs.
User-driven database of knitting and crochet patterns, including many patterns for mathematics illustrations, that you can find by searching "Mathematics". Requires a free account to browse. Users can contribute patterns and track projects.
Contains a gallery of illustrations of mathematical concepts ranging through all areas of mathematics, a catalogue of math related exhibitions as well as films, 3D printable files, and other medias.
Maths pictures contain a mathematical description of their content. Authors also have the possibility to include the necessary files to reproduce them – be it high resolution pictures, equations behind them or source files for visualization programs.
