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.
