Constructive Galois connections: taming the Galois connection framework for mechanized metatheory [PDF]

open access: yesACM SIGPLAN International Conference on Functional Programming, 2015
Galois connections are a foundational tool for structuring abstraction in semantics and their use lies at the heart of the theory of abstract interpretation.

Complexity calculation of coding and information security system based on threshold secret sharing scheme used for electronic voting

open access: yesAdvanced Engineering Research, 2017
Introduction . One of the tasks arising in cryptography is to ensure the safe and honest conduct of e-voting. This procedure provides that voters submit their votes electronically - for example, through electronic terminals.

The Projective Character Tables of a Solvable Group 26:6×2

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2019
The Chevalley–Dickson simple group G24 of Lie type G2 over the Galois field GF4 and of order 251596800=212.33.52.7.13 has a class of maximal subgroups of the form 24+6:A5×3, where 24+6 is a special 2-group with center Z24+6=24. Since 24 is normal in 24+6:

Arithmetic gauge theory: A brief introduction [PDF]

open access: yesModern Physics Letters A, 2017
Much of arithmetic geometry is concerned with the study of principal bundles. They occur prominently in the arithmetic of elliptic curves and, more recently, in the study of the Diophantine geometry of curves of higher genus.

Finding Minimum‐Cost Explanations for Predictions Made by Tree Ensembles

open access: yesSoftware: Practice and Experience, EarlyView.
ABSTRACT The ability to reliably explain why a machine learning model arrives at a particular prediction is crucial when used as decision support by human operators of critical systems. The provided explanations must be provably correct, and preferably without redundant information, called minimal explanations.

A Vulnerability Lens for Intuitive‐Logic Scenarios

open access: yesFUTURES &FORESIGHT SCIENCE, Volume 8, Issue 1, April 2026.
ABSTRACT Exploration of possibilities by means of intuitive logic is hampered by a large number of scenarios, which easily exceed the limits imposed by human bounded rationality. While many practitioners constrain their scenarios within a 2 × 2 $2\times 2$ matrix by design, more structured approaches point to rationales such as eliminating ...

Bridging 4D QFTs and 2D VOAs via 3D high-temperature EFTs

open access: yesJournal of High Energy Physics
The high-temperature limit of the superconformal index, especially on higher sheets, often captures useful universal information about a theory. In 4d N = 2 $$ \mathcal{N}=2 $$ superconformal field theories with fractional r-charges, there exists a ...

An effective method to study the Hopf-Galois module structure of certain extensions of fields

open access: yes
We develop a method to compute a basis of the associated order in a Hopf Galois structure H of the ring of integers O_L of an extension of number or p-adic fields L/K.

Attribute Implication Bases From Galois Connection Structures

open access: yesMathematical Methods in the Applied Sciences, Volume 49, Issue 4, Page 2729-2753, 15 March 2026.
ABSTRACT Modeling knowledge systems by determining relationships among key variables have been and currently is a fundamental and nontrivial challenge in real‐world scenarios. Many approaches have been developed to reach this goal, but many of them are heuristic and require of alternative procedures to provide robust and tractable rules.

Simplification of exponential factors of irregular connections on P1${\mathbb {P}}^1$

open access: yesBulletin of the London Mathematical Society, Volume 58, Issue 3, March 2026.
Abstract We give an explicit algorithm to reduce the ramification order of any exponential factor of an irregular connection on P1$\mathbb {P}^1$, using the same types of basic operations as in the Katz–Deligne–Arinkin algorithm for rigid irregular connections.
