Fuzzy Approximating Spaces [PDF]
Journal of Applied Mathematics, 2014 Relationships between fuzzy relations and fuzzy topologies are deeply researched. The concept of fuzzy approximating spaces is introduced and decision conditions that a fuzzy topological space is a fuzzy approximating space are obtained.

Massless monopoles and the moduli space approximation [PDF]
, 2001 We investigate the applicability of the moduli space approximation in theories with unbroken non-Abelian gauge symmetries. Such theories have massless magnetic monopoles that are manifested at the classical level as clouds of non-Abelian field ...

Interpolated scales of approximation spaces for regular elliptic operators on compact manifolds
Karpatsʹkì Matematičnì Publìkacìï, 2014 We define the interpolated scales of approximation spaces, generated by regular elliptic operators on compact manifolds. The appropriate Bernstein-Jackson inequalities and application to spectral approximations of regular elliptic operators are ...

A New Analytical Approximation of the Fluid Antenna System Channel [PDF]
IEEE Transactions on Wireless Communications, 2022 Fluid antenna systems (FAS) are an emerging technology that promises a significant diversity gain even in the smallest spaces. It consists of a freely moving antenna in a small linear space to pick up the strongest received signal.

On the Eikonal Approximation in AdS Space [PDF]
, 2010 We explore the eikonal approximation to graviton exchange in AdS_5 space, as relevant to scattering in gauge theories. We restrict ourselves to the regime where conformal invariance of the dual gauge theory holds, and to large 't Hooft coupling where the

Parallel Magnetic Resonance Imaging as Approximation in a Reproducing Kernel Hilbert Space [PDF]
, 2014 In Magnetic Resonance Imaging (MRI) data samples are collected in the spatial frequency domain (k-space), typically by time-consuming line-by-line scanning on a Cartesian grid.

Silent MST approximation for tiny memory [PDF]
, 2020 In network distributed computing, minimum spanning tree (MST) is one of the key problems, and silent self-stabilization one of the most demanding fault-tolerance properties. For this problem and this model, a polynomial-time algorithm with $O(\log^2\!n)$

The Chebyshev Set Problem in Riesz Space
Journal of Function Spaces, 2022 In this paper, we mainly study the best approximation theory in Riesz space, which is not constructed by the norm, but only rely on the order structure.

International Journal of Approximate Reasoning, 2019 In this paper, we discuss the relationship between different types of reduction and set definability. We recall the definition of a decision reduct, a γ-decision reduct, a decision bireduct and a γ-decision bireduct in a Pawlak approximation space and ...

Generalization of Pawlak’s Approximations in Hypermodules by Set-Valued Homomorphisms
Foundations of Computing and Decision Sciences, 2017 The initiation and majority on rough sets for algebraic hyperstructures such as hypermodules over a hyperring have been concentrated on a congruence relation.
