A novel pessimistic multigranulation roughness by soft relations over dual universe
AIMS Mathematics, 2023 A multigranulation rough set over two universes delivers a unique perspective on the combination of multigranulation information. This paper presents the pessimistic multignualtion rough set over dual universes based on soft binary relations.

Identities for field extensions generalizing the Ohno-Nakagawa relations [PDF]
, 2015 In previous work, Ohno conjectured, and Nakagawa proved, relations between the counting functions of certain cubic fields. These relations may be viewed as complements to the Scholz reflection principle, and Ohno and Nakagawa deduced them as consequences

Compact Binary Relation Representations with Rich Functionality [PDF]
, 2012 Binary relations are an important abstraction arising in many data representation problems. The data structures proposed so far to represent them support just a few basic operations required to fit one particular application.

High-Order Multipole and Binary Love Number Universal Relations
Universe, 2021 Using a data set of approximately 2 million phenomenological equations of state consistent with observational constraints, we construct new equation-of-state-insensitive universal relations that exist between the multipolar tidal deformability parameters

Фінансово-кредитна діяльність: проблеми теорії та практики, 2020 The methods of making a collective decision and choosing group matching procedures are analyzed. It is assumed that the methods of evaluation are given in the scales of qualitative order, including the binary relations of alternatives.

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.

AIMS Mathematics, 2020 In this paper, we introduce the concept of Suzuki type $\mathcal{Z_\mathcal{R}}$-contraction by unifying the definitions of Suzuki type $\mathcal{Z}$-contraction and $\mathcal{Z_\mathcal{R}}$-contraction and also provide examples to highlight the ...

Algebras of Binary Isolating Formulas for Tensor Product Theories
Известия Иркутского государственного университета: Серия "Математика", 2022 Algebras of distributions of binary isolating and semi-isolating formulae are derived objects for a given theory and reflect binary formula relations between 1-type realizations.

Quasiorders, Tolerance Relations and Corresponding “Partitions” [PDF]
, 2016 The paper deals with a generalization of the notion of partition for wider classes of binary relations than equivalences: for quasiorders and tolerance relations. The counterpart of partition for the quasiorders is based on a generalization of the notion

Algebras of Binary Isolating Formulas for Theories of Root Products of Graphs
Известия Иркутского государственного университета: Серия "Математика", 2021 Algebras of distributions of binary isolating and semi-isolating formulas are derived objects for given theory and reflect binary formula relations between realizations of 1-types.
