The notion of endomorphism congruence considered in this paper has a close connection with the notion of result. To say most generally, results are fractions such that their numerators are elements of a certain linear space while their denominators are injective endomorphisms of that space.

Survey on comultiplication modules [PDF]
The concept of comultiplication (as a dual notion of multiplication) modules was introduced and studied by H. Ansari-Toroghy and F. Farshadifar in 2007. This notion has obtained a great attention by many authors and now there is a considerable amount of ...

Ordered Structures and Projections
We associate a covering relation to the usual order relation defined in the set of all idempotent endomorphisms (projections) of a finite-dimensional vector space. A characterization is given of it.

The dynamic of a Lie group endomorphism
For a given endomorphism φ on a connected Lie group G this paper studies several subgroups of G that are intrinsically connected with the dynamic behavior of φ.

On geometry of sub-Riemannian η-Einstein manifolds
On a sub-Riemannian manifold of contact type a connection with torsion is considered, called in the work a Ψ-connection. A Ψ-connection is a particular case of an N-connection.

On exterior powers of endomorphisms
Let \(V\) be an n-dimensional vector space and \(T \in \Hom(V,V)\). The first result shows that if \(C_m(T)\), the m-th compound of \(T\), possesses a basis of eigenvectors, then lt possesses a basis consisting of decomposable eigenvectors in the m-th Grassmann space over \(V\). The paper also contains a simplified proof of a recent result of \textit{S.

On semigroups of graph endomorphisms
AbstractIt is shown that given a finite or infinite graph H and a subsemigroup B of its endomorphism semigroup End H, there exists a graph G such that 1.(i)|H is an induced subgraph of G,2.(ii)|H is stable by every f ϵ End G,3.(iii)|every f ϵ End G is uniquely determined by its restriction to H,4.(iv)|the restriction of End G to H is precisely B.
