Locally ringed spaces of the form SpecR are called afﬁne schemes; locally ringed spaces that are locally of the form SpecR are called schemes. Schemes are the fundamental objects of study in algebraic geometry. WebDec 1, 2024 · Combining this with the fact that a fair number of nice theorems we know for coherent sheaves on schemes in the locally noetherian case admit generalizations to locally finitely presented sheaves in the non-noetherian case (for instance, the sheaf hom result you link), it is useful to relax our finiteness condition a little bit from coherence to locally finite … l\u0027hermitage apartments milwaukee

WebOct 6, 2008 · 4N30 DRL. In this lecture I'll define relative Riemann-Zariski spaces attached to a morphism of schemes and generalizing the classical Riemann-Zariski space of a field over C. We will see that similarly to the classical RZ spaces, the relative ones can be described either as projective limits of schemes in the category of locally ringed spaces ... WebThe aim of this work is to give a generalization of Gabriel’s theorem for twisted sheaves over smooth varieties. We start by showing that we can reconstruct a variety X from the category Coh(X,α) of coherent α−twisted sheaves over X.
