Graded Rings The package &GradedRingForHomalg; defines the classes of graded rings, ring elements and matrices over such rings. These three objects can be used as data structures defined in &MatricesForHomalg; on which the &homalg; project can rely to do homological computations over graded rings.

The graded rings most prominently can be used with methods known from general &homalg; rings. The methods for doing the computations are presented in the appendix (), since they are not for external use. The new attributes and operations are documented here.

Since the objects inplemented here are representations from objects elsewhere in the &homalg; project (i.e. &MatricesForHomalg;), we want to stress that there are many other operations in &MatricesForHomalg;, which can be used in connection with the ones presented here. A few of them can be found in the examples and the appendix of this documentation.
