Ordinal notions of submodularity [PDF]
, 2008 We consider several ordinal formulations of submodularity, defined for arbitrary binary relations on lattices. Two of these formulations are essentially due to Kreps [Kreps, D.M., 1979.

Matroidal structure of generalized rough sets based on symmetric and transitive relations [PDF]
, 2012 Rough sets are efficient for data pre-process in data mining. Lower and upper approximations are two core concepts of rough sets. This paper studies generalized rough sets based on symmetric and transitive relations from the operator-oriented view by ...

K-causality coincides with stable causality
, 2008 It is proven that K-causality coincides with stable causality, and that in a K-causal spacetime the relation K^+ coincides with the Seifert's relation. As a consequence the causal relation "the spacetime is strongly causal and the closure of the causal ...

Upper Semicontinuous Extensions of Binary Relations [PDF]
, 2002 Suzumura shows that a binary relation has a weak order extension if and only if it is consistent. However, consistency is demonstrably not sufficient to extend an upper semi-continuous binary relation to an upper semicontinuous weak order. Jaffray proves

Refining Transitive and Pseudo-Transitive Relations at Web Scale
, 2021 The publication of knowledge graphs on the Web in the form of RDF datasets, and the subsequent integration of such knowledge graphs are both essential to the idea of Linked Open Data. Combining such knowledge graphs can result in undesirable graph structures and even in logical inconsistencies.

Advanced Intelligent Discovery, EarlyView.This study integrates random matrix theory (RMT) and principal component analysis (PCA) to improve the identification of correlated regions in HIV protein sequences for vaccine design. PCA validation enhances the reliability of RMT‐derived correlations, particularly in small‐sample, high‐dimensional datasets, enabling more accurate detection of ...

The combinational structure of non-homogeneous Markov chains with countable states
International Journal of Mathematics and Mathematical Sciences, 1983 Let P(s,t) denote a non-homogeneous continuous parameter Markov chain with countable state space E and parameter space [a,b], −∞

Journal of Function Spaces, 2020 In this article, we prove some relation-theoretic results on coincidence and common fixed point for a nonlinear contraction employing a locally finitely T-transitive binary relation, where T stands for a self-mapping on the underlying metric space.
