Notes on schematic finite spaces
Fernando Sancho, Pedro Sancho
The schematic finite spaces are those finite ringed spaces where a theory of quasi-coherent modules can be developed with minimal natural conditions. We give various characterizati…
Mittag-Leffler functors of modules
C. Sancho, F. Sancho, P. Sancho
Finite modules, finitely presented modules and Mittag-Leffler modules are characterized by their behaviour by tensoring with direct products of modules. In this paper, we study and…
Functorial characterization of Mittag-Leffler modules
Carlos Sancho, Fernando Sancho, Pedro Sancho
We give a functorial characterization of Mittag-Leffler modules and strict Mittag-Leffler modules.
Flat SML modules and reflexive functors
Carlos Sancho, Fernando Sancho, Pedro Sancho
We give some functorial characterizations of flat strict Mittag-Leffler modules. We characterize reflexive functors of modules with similar tools, definitions and theorems.
Geometric characterization of flat modules
Carlos Sancho, Fernando Sancho, Pedro Sancho
Let be a commutative ring. Roughly speaking, we prove that an -module is flat iff it is a direct limit of -module affine algebraic varieties, and is a flat Mittag…
