Triangular norm-based intuitionistic fuzzy BE-algebras and filters [PDF]

Notes on IFS
In this paper, intuitionistic fuzzy BE-algebra that a generalization of the BCK-algebra is introduced with respect to t-norms and t-conorms. The various algebraic properties of triangular norm-based intuitionistic fuzzy BE-algebras are studied in detail,

Bounds for the norm of lower triangular matrices on the Cesàro weighted sequence space [PDF]

Journal of Inequalities and Applications, 2017
This paper is concerned with the problem of finding bounds for the norm of lower triangular matrix operators from l p ( w ) $l_{p}(w)$ into c p ( w ) $c_{p} (w)$ , where c p ( w ) $c_{p}(w)$ is the Cesàro weighted sequence space and ( w n ) $(w_{n})$ is ...

Triangular norms on finite lattices

Fuzzy Sets and Systems
This article intends to characterize triangular norms on a finite lattice. We first give a method for generating a triangular norm on an atomistic lattice by the values of atoms. Then we prove that every triangular norm on a non-Boolean atomistic lattice is not left-continuous and $T_M$ is the uniquely left-continuous triangular norm on an atomistic ...

Uniform bounds on the 1-norm of the inverse of lower triangular Toeplitz matrices [PDF]

, 2011
A uniform bound on the 1-norm is given for the inverse of a lower triangular Toeplitz matrix with non-negative monotonically decreasing entries whose limit is zero. The new bound is sharp under certain specified constraints.

A Parameter-tunable Triangular Norm with Monotonic Genes

Journal of Harbin University of Science and Technology, 2023
In order to study the optimization of Zadeh operator, a definition of parameter-tunable triangular norm with monotonic genes is given.First, we defined a kind of triangular norm Fλin the general sense generated by monotone functions using elementary ...

Triangular Norm-Based Elements on Bounded Lattices

Axioms, 2023
In this study, we introduce the notion of the T-irreducible element as a generalization of the notion of the meet-irreducible element in complete lattices. We derive some related properties of these elements and T-prime elements.

A Probability Integral on η-fuzzy Measure

Journal of Harbin University of Science and Technology, 2022
For the study of relevant definitions and theorems of fuzzy integrals, a fuzzy measure is first defined; then a pair of optimized Einstein operators of the form are designed, which are λ-fuzzy quasiproduct operator and λ-fuzzy quasisum operator ...

Maximum norm a posteriori error estimate for a 2d singularly perturbed semilinear reaction-diffusion problem [PDF]

, 2008
A singularly perturbed semilinear reaction-diffusion equation, posed in the unit square, is discretized on arbitrary nonuniform tensor-product meshes. We establish a second-order maximum norm a posteriori error estimate that holds true uniformly in the ...

On Discrete Presheaf Monads

Axioms, 2023
For a quantale I, which is a unit interval endowed with a continuous triangular norm and the Barr extension β¯I of the ultrafilter monad to I-Rel, a characterization of the discrete presheaf monad associated to β¯I is given. It is also proved that, when &
