Rationality of hypersurfaces: a new website
After seeing John Christian Ottem, Stable irrationality of quartic sixfolds on the arXiv yesterday, I was reminded of my plans a little while ago to make a website like mgnbar.info surveying the state of the art on a precise question. Inspiration for this I found in
- Francesco Russo, Rationality of cubic fourfolds via Trisecant Flops
- Olivier Debarre, On rationality problems
Without further ado, see rationality.fanography.info. It is just a single page, with features very much like mgnbar.info. I’m not sure I like the methods overview, maybe I will get rid of it at some point.
