On the class of fuzzy number sequences [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2019 We introduce the notion of p-bounded variation of fuzzy real number sequences, bvFp, for 1 ...

Subobjects and Compactness in Point-Free Convergence
Journal of Mathematics, 2023 We consider subobjects in the context of point-free convergence (in the sense of Goubault-Larrecq and Mynard), characterizing extremal monomorphisms in the opposite category of that of convergence lattices.

Three-Step Derivative-Free Method of Order Six
Foundations, 2023 Derivative-free iterative methods are useful to approximate the numerical solutions when the given function lacks explicit derivative information or when the derivatives are too expensive to compute.

On Derivative Free Multiple-Root Finders with Optimal Fourth Order Convergence
Mathematics, 2020 A number of optimal order multiple root techniques that require derivative evaluations in the formulas have been proposed in literature. However, derivative-free optimal techniques for multiple roots are seldom obtained.

Seventh Order Derivative-Free Methods for Non-differentiable Operator Equations
European Journal of Mathematical Analysis, 2023 In nonlinear problems where function’s derivatives are difficult or expensive to compute, derivative-free iterative methods are good options to find the numerical solution.

Convergence of Derivative-Free Iterative Methods with or without Memory in Banach Space
Foundations, 2023 A method without memory as well as a method with memory are developed free of derivatives for solving equations in Banach spaces. The convergence order of these methods is established in the scalar case using Taylor expansions and hypotheses on higher ...

On Lacunary p-Absolutely Summable Fuzzy Real-Valued Double Sequence Space
Demonstratio Mathematica, 2014 In this article, we introduce the class of p-absolutely summable fuzzy real valued double sequence (2lp)Fθ We have studied some algebraic properties like solid, symmetric, convergence free, sequence algebra.

New type of difference sequence spaces of fuzzy real numbers
Mathematical Modelling and Analysis, 2009 In this paper we introduce the natation difference operator Δrn(m ≥ 0, an integer) for studying properties of some sequence spaces. We define the sequence spaces l ∞ F (Δm), cF(Δm), cF o(Δm) and investigate their properties like solid‐ness, convergence ...
