Wijsman regularly ideal convergence of double sequences of sets
Journal of Intelligent & Fuzzy Systems, 2019 In this paper, we introduce the notions of regularly ( I W 2 , I W ) -convergence, regularly ( I W 2 * , I W * ) -convergence, regularly ( I W 2 , I W ) -Cauchy and regularly ( I W 2 * , I W * ) -Cauchy double sequence of sets and investigate the ...

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objectives Focal cortical dysplasia (FCD) is the most common etiology of drug‐resistant epilepsy in children. Focal to bilateral tonic–clonic seizures (FBTCS) mark a high risk of drug‐resistant epilepsy and involve thalamocortical circuitry in their generation and propagation.

Demonstratio Mathematica, 2014 In this work, using the concept of I-convergence and using the concept of rough convergence, we introduced the notion of rough I-convergence and the set of rough I-limit points of a sequence and obtained two rough I-convergence criteria associated with ...

On I-quotient mappings and I-cs'-networks under a maximal ideal
Applied General Topology, 2020 Let I be an ideal on N and f : X → Y be a mapping. f is said to be an I-quotient mapping provided f−1(U) is I-open in X, then U is I-open in Y . P is called an I-cs′-network of X if whenever {xn}n∈N is a sequence I-converging to a point x ∈ U with U open

Gravity‐Dependent Modulation of Downbeat Nystagmus: Insights From Velocity‐Storage Dysfunction
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Downbeat nystagmus varies with head position, a phenomenon termed gravity‐dependent modulation. We aimed to clarify its mechanism using a velocity‐storage model. Methods In 10 patients with downbeat nystagmus due to cerebellar disorders, we recorded eye movements at different pitch‐ and roll‐axis head positions.

Spaces not distinguishing ideal pointwise and $\sigma$-uniform convergence
, 2023 We examine topological spaces not distinguishing ideal pointwise and ideal $\sigma$-uniform convergence of sequences of real-valued continuous functions defined on them. For instance, we introduce a purely combinatorial cardinal characteristic (a sort of

On Lacunary ideal convergence of some sequences
, 2017 The idea of statistical convergence of real sequences was pr e ented by Fast [ 2] as a generalization of ordinary convergence. It is a practical tool to study the problems rel ated to convergence of numerical sequences by means of the concept of density.

On Convergence with respect to an Ideal and a Family of Matrices [PDF]
International Journal of Analysis, 2014 P. Das et al. recently introduced and studied the notions of strong AI-summability with respect to an Orlicz function F and AI-statistical convergence, where A is a nonnegative regular matrix and I is an ideal on the set of natural numbers. In this paper, we will generalise these notions by replacing A with a family of matrices and F with a family of ...
