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…
Functors of modules associated with flat and projective modules II
Adrián Gordillo-Merino, José Navarro, Pedro Sancho
Let be an associative ring with unit. Given an -module , we can associate the following covariant functor from the category of -algebras to the category of abelian gro…
Reflexivity of modules
Adrián Gordillo-Merino, José Navarro, Pedro Sancho
We consider modules as functors in the following way: if is a (left) -module, let be the functor of modules defined by $\,\mathcal…
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…
A remark on the invariant theory of real Lie groups
A. Gordillo, J. Navarro, P. Sancho
We present a simple remark that assures that the invariant theory of certain real Lie groups coincides with that of the underlying affine, real algebraic groups. In particular, thi…
Left-exact Mittag-Leffler functors of modules
Adrián Gordillo, José Navarro, Pedro Sancho
Let be an associative ring with unit. This paper deals with various aspects of the category of functors of -modules; that is, the category of additive and covariant…
