Topological and scheme-theoretic properties of the -graded Proj construction
Felix Goebler
We generalize the topological description of the -graded Proj construction to the multigraded Proj construction for factorially graded rings that are graded by finitely…

Relevant maps and the algebraic skeleton of simplicial toric prevarieties
Felix Goebler
Morphisms between schemes arising from multigraded rings are essential for understanding geometric relationships in algebraic geometry, yet a systematic theory for such maps has be…
