A characterization of adjunction in a many-valued modal system
CQD Revista Eletrônica Paulista de MatemáticaGalois connections are pairs of functions, defined over ordered sets, that preserve some particular aspects. They are studied in the context of algebraic structures.

Abelian threefolds with imaginary multiplication
Journal of the London Mathematical Society, Volume 114, Issue 1, July 2026.Abstract Let A$A$ be an abelian threefold defined over a number field K$K$ with potential multiplication by an imaginary quadratic field M$M$. Under mild assumptions on K$K$, if A$A$ has signature (2,1) and the multiplication by M$M$ is defined over KM$KM$, we attach to A$A$ an elliptic curve defined over K$K$ with potential complex multiplication by M$

On the Lang–Trotter conjecture for Siegel modular forms
Mathematika, Volume 72, Issue 3, July 2026.Abstract Let f$f$ be a genus‐two cuspidal Siegel eigenform. We prove an adelic open image theorem for the compatible system of Galois representations associated with f$f$, generalizing the results of Ribet and Momose for elliptic modular forms. Using this result, we investigate the distribution of the Hecke eigenvalues ap$a_p$ of f$f$, and obtain upper

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 ...

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-

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 ...

A Meta-Logical Framework for the Equivalence of Syntactic and Semantic Theories
PhilosophiesThis paper introduces a meta-logical framework—based on the theory of institutions (a categorical version of abstract model theory)—to be used as a tool for the formalization of the two main views regarding the structure of scientific theories, namely ...

Formal Context Transforms and Their Affordances for Exploratory Data Analysis
MathematicsConsider a formal context (G, M, I) as the basic mechanism to capture information about a set G of objects, a set M of attributes and the relation I ∈ G × M between them. Traditional use of Formal Concept Analysis has some shortcomings in its information-
