L(1, 2)-labeling numbers on square of cycles

open access: yesAKCE International Journal of Graphs and Combinatorics, 2020
For two positive numbers d and m, an m-L(1, d)-labeling of a graph G is a mapping such that if and if The span of f is the maximum difference among the numbers assigned by f.

Dual Directional Structured Products [PDF]

open access: yesSSRN Electronic Journal, 2012
We analyze and value dual directional structured products – or simply dual directionals (DDs) – which have been issued in large amounts since the beginning of 2012. DDs evolved out of another type of structured product called absolute return barrier notes; however, DDs lack principal protection and have different embedded options positions, which are ...

Triangular Norm-Based Elements on Bounded Lattices

open access: yesAxioms, 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.

Groupoids: Direct products, semidirect products and solvability

open access: yesAlgebra and Discrete Mathematics, 2022
We present some constructions of groupoids such as: direct product, semidirect product and give necessary and sufficient conditions for a groupoid to be embedded into a direct product of groupoids. Also, we establish necessary and sufficient conditions to determine when a semidirect product is direct.

Principal arc analysis on direct product manifolds [PDF]

open access: yes, 2011
We propose a new approach to analyze data that naturally lie on manifolds. We focus on a special class of manifolds, called direct product manifolds, whose intrinsic dimension could be very high.

A strong direct product theorem for quantum query complexity [PDF]

open access: yes, 2011
We show that quantum query complexity satisfies a strong direct product theorem. This means that computing $k$ copies of a function with less than $k$ times the quantum queries needed to compute one copy of the function implies that the overall success ...

Super Connected Direct Product of Graphs and Cycles

open access: yesAxioms, 2022
The topology of an interconnection network can be modeled by a graph G=(V(G),E(G)). The connectivity of graph G is a parameter used to measure the reliability of a corresponding network. The direct product is an important graph product. This paper mainly

New Concepts of Picture Fuzzy Graphs with Application

open access: yesMathematics, 2019
The picture fuzzy set is an efficient mathematical model to deal with uncertain real life problems, in which a intuitionistic fuzzy set may fail to reveal satisfactory results.
