EIRENE is an open-source platform for computational homology. It is part of a long term, global effort to introduce algebraic topology, the mathematics of abstract space, to modern problems in engineering and applied science. Explicit representation and 3D visualization of homological generators, as in the case of a persistent 1-cycle embedded in the Eurasian continent below, is an important branch of this project. Eirene is currently in beta, with limited scope and functionality. We anticipate many additions over the coming months, so please check back frequently for updates. If there are any features you think we should have but don't, or if you find potential bugs, please let us know! Our contact information can be found above.
