Every affine graded ring has a Hodge algebra structure. (English) Zbl 0619.13005
Main result: Let \(A=\oplus_{n\geq 0}A_ n\quad be\) a graded ring, finitely generated over a field \(A_ 0=k\). Then A has a Hodge algebra structure over k whose poset consists of homogeneous elements.
There is also a simple proof of an earlier result by the author: Every affine semigroup ring has a Hodge algebra structure.
