Graded rings and databases

The graded ring database page has lists of graded rings of polarised varieties, such as K3 surfaces and Fano 3-folds and 4-folds. This poster gives a flavour of some of the topics. The previous version is linked here.

The homepage uses the computer algebra system Magma. You can use it on-line at magma/calc. If you have Magma, then its handbook explains how to search its own databases. Information on past conferences on this graded ring material and on Magma is here.
