A short note on Simulation and Abstraction [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2013
This short note is written in celebration of David Schmidt's sixtieth birthday. He has now been active in the program analysis research community for over thirty years and we have enjoyed many interactions with him. His work on characterising simulations

Relating non-Hermitian and Hermitian quantum systems at criticality

open access: yesSciPost Physics Core, 2023
We demonstrate three types of transformations that establish connections between Hermitian and non-Hermitian quantum systems at criticality, which can be described by conformal field theories (CFTs).

On Contradiction and Inclusion Using Functional Degrees

open access: yesInternational Journal of Computational Intelligence Systems, 2020
The notion of inclusion is a cornerstone in set theory and therefore, its generalization in fuzzy set theory is of great interest. The degree of f-inclusion is one generalization of such a notion that differs from others existing in the literature ...

Lattice-Valued Topological Systems as a Framework for Lattice-Valued Formal Concept Analysis

open access: yesJournal of Mathematics, 2013
Recently, Denniston, Melton, and Rodabaugh presented a new categorical outlook on a certain lattice-valued extension of Formal Concept Analysis (FCA) of Ganter and Wille; their outlook was based on the notion of lattice-valued interchange system and a ...

Asymptotic distribution of traces of singular moduli

open access: yesDiscrete Analysis, 2022
Asymptotic distribution of traces of singular moduli, Discrete Analysis 2022:4, 14 pp. This paper concerns the modular $j$-function, a famous function that is fundamental to algebraic number theory and has remarkable connections to other areas of ...

Representation of Fuzzy Concept Lattices in the Framework of Classical FCA

open access: yesJournal of Applied Mathematics, 2013
We describe a representation of the fuzzy concept lattices, defined via antitone Galois connections, within the framework of classical Formal Concept Analysis. As it is shown, all needed information is explicitly contained in a given formal fuzzy context

ESSENTIAL AND RETRACTABLE GALOIS CONNECTIONS [PDF]

open access: yesJournal of Algebra and Its Applications, 2013
For bounded lattices, we introduce certain Galois connections, called (cyclically) essential, retractable and UC Galois connections, which behave well with respect to concepts of module-theoretic nature involving essentiality. We show that essential retractable Galois connections preserve uniform dimension, whereas essential retractable UC Galois ...

On Constructivity of Galois Connections [PDF]

open access: yes, 2017
Abstract interpretation-based static analyses rely on abstract domains of program properties, such as intervals or congruences for integer variables. Galois connections (GCs) between posets provide the most widespread and useful formal tool for mathematically specifying abstract domains.
