Résumé :
Noncommutative algebraic geometry studies a certain quotient category R-qgr of the category of graded R-modules which for commutative R is equivalent to the category of quasi-coherent sheaves by a famous theorem of Serre. For a large class of graded algebras, the so-called schematic algebras, we are able to construct a kind of scheme such that the coherent sheaves on it are equivalent to R-qgr. We give a brief survey on the results so-far on schematic algebras and include some new results on cohomological properties of Auslander-Gorenstein algebras which might be useful in determining the strength of the schematic property.
