Indecomposability of derived categories for arbitrary schemes
Ana Cristina López Martín, Fernando Sancho de Salas
We extend the criterion of Kawatani and Okawa for indecomposability of the derived category of a smooth projective variety to arbitrary schemes. For relative schemes, we also give…
Relative perfect complexes
Leovigildo Alonso, Ana Jeremias, Fernando Sancho
Let be a morphism of concentrated schemes. We characterize -perfect complexes as those such that the functor $\mathcal{E} \otimes^{\mathbf{L}}_X…
Universal ringed spaces
J. Sánchez González, F. Sancho de Salas
We construct affine spaces, projective spaces and grassmannians in the ca\-te\-gory of ringed spaces. We show how finite posets and sheaves of rings on them appear in a natural way…
Ringed Finite Spaces
Fernando Sancho de Salas
A ringed finite space is a ringed space whose underlying topological space is finite. The category of ringed finite spaces contains, fully faithfully, the category of finite topolo…
