Evaluation and analysis of the computation cost of linear network coding

Tongxin xuebao, 2011
The complexity of algebraic operation methods on Galois fields was analyzed and the operation mechanism of linear network coding was anatomized.Based on deterministic network coding data transmission and random network coding data transmission for single-

A characterization of adjunction in a many-valued modal system

CQD Revista Eletrônica Paulista de Matemática
Galois connections are pairs of functions, defined over ordered sets, that preserve some particular aspects. They are studied in the context of algebraic structures.

Galois connections categorically

Journal of Pure and Applied Algebra, 1990
This is an expansion of a previous paper [Lect. Notes Comput. Sci. 239, 122-134 (1986; Zbl 0615.06002)]. It is a somewhat discursive discussion of Galois connections in (briefly) partially ordered sets, concrete categories, and categories. In concrete categories the authors consider only Galois connections commuting with the forgetful functors, which ...

Ricerche di matematica con Giuseppina Varone

Science & Philosophy, 2013
In memory of the researcher Pina Varone, I present the research carried out together for over 20 years. Some relevant issues and applicants were: the connection between teaching and research, and as an in-depth teaching emerge new research topics; the ...

Wilson's map operations on regulat dessins and cyclotomic fields of definition

, 2009
Dessins d’enfants can be seen as bipartite graphs embedded in compact orientable surfaces. According to Grothendieck and others, a dessin uniquely determines a complex structure on the surface, even an algebraic structure as a projective algebraic curve ...

Some order dualities in logic, games and choices [PDF]

We first present the concept of duality appearing in order theory, i.e. the notions of dual isomorphism and of Galois connection. Then, we describe two fundamental dualities, the duality extension/intention associated with a binary relation between two ...

On the Galoisian Structure of Heisenberg Indeterminacy Principle [PDF]

, 2013
We revisit Heisenberg indeterminacy principle in the light of the Galois-Grothendieck theory for the case of finite abelian Galois extensions. In this restricted framework, the Galois-Grothendieck duality between finite K-algebras split by a Galois ...

Hopf-Galois module structure of tame Cp×Cp extensions [PDF]

, 2016
Let $ p $ be an odd prime number, $ K $ a number field containing a primitive $ p^{th} $ root of unity, and $ L $ a Galois extension of $ K $ with Galois group isomorphic to $ C_{p} \times C_{p} $. We study in detail the local and global structure of the
