Title




A new dimension for schematic algebras
 
Author




 
Abstract




Schematic algebras are graded algebras with a finite number of twosided homogeneous Oresets satisfying a precise condition. In this note we study the least possible number of Oresets which satisfy this condition and call it the schematic dimension. If R is commutative, then the schematic dimension of R equals the dimension of its associated projective variety. We also calculate the schematic dimension of homogenized enveloping algebras and Weyl algebras, and observe that they behave differently.
