A characterisation of Euclidean normed planes via bisectors
Javier Cabello Sánchez, Adrián Gordillo-Merino
Our main result states that whenever we have a non-Euclidean norm on a two-dimensional vector space , there exists some such that for every ,…
Dimensional curvature identities in Fedosov geometry
Adrián Gordillo-Merino, Raúl Martínez-Bohórquez, José Navarro-Garmendia
The curvature tensor of a symplectic connection, as well as its covariant derivatives, satisfy certain identities that hold on any manifold of dimension less than or equal to a fix…
On invariant operations of Fedosov structures
Adrián Gordillo-Merino, Raúl Martínez-Bohórquez, José Navarro-Garmendia
In this paper we study invariant local operations that can performed on a Fedosov manifold, with a particular emphasis on tensor-valued operations (also known as natural tensors).…
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…
