Difference sets are not multiplicatively closed
Discrete Analysis, 2016 Difference sets are not multiplicatively closed, Discrete Analysis 2016:17, 20pp. The famous sum-product problem of Erdős and Szemerédi asks the following. Let $A$ be a set of $n$ real numbers.

Compact Operators on the Sets of Fractional Difference Sequences
Sakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2019 The sets of fractional difference sequences have been studied in the literature recently. In this work, some identities or estimates for the operator norms and the measure of noncompactness of certain operators on difference sets of sequences of ...

Testing the Difference of Means of Populations With Respect to Intuitionistic Fuzzy Sets
International Journal of Analysis and Applications, 2022 In this study, the tests of statistical hypotheses with crisp data using small samples are extended to with the membership function and the non-membership function of the intuitionistic fuzzy set. The test procedure of statistical hypotheses for means of

On Multipliers of Difference Sets [PDF]
Canadian Journal of Mathematics, 1965 Multipliers are useful in constructing difference sets as well as in impossibility proofs. The existence of a fixed set facilitates their application, so that the results of this paper should prove to be useful in numerical work concerning difference sets.Let G be a group which we shall write multiplicatively.

Almost Difference Sets and Reversible Divisible Difference Sets [PDF]
, 1992 Let G be a group of order mn and N a subgroup of G of order n. If D is a k-subset of G, then D is called a (m, n, k, λ1, λ2) divisible difference set (DDS) provided that the differences dd\u27-1 for d, d\u27 ∈ D, d ≠ d\u27 contain every nonidentity ...

On Some New Almost Difference Sets Constructed from Cyclotomic Classes of Order 12
Recoletos Multidisciplinary Research Journal, 2023 Almost Difference Sets have extensive applications in coding theory and cryptography. In this study, we introduce new constructions of Almost Difference Sets derived from cyclotomic classes of order 12 in the finite field GF(q), where q is a prime ...

A New gH-Difference for Multi-Dimensional Convex Sets and Convex Fuzzy Sets
Axioms, 2019 In the setting of Minkowski set-valued operations, we study generalizations of the difference for (multidimensional) compact convex sets and for fuzzy sets on metric vector spaces, extending the Hukuhara difference.

Additive Structure of Sparse-Digit Fractal Sets: Sumsets, Difference Sets, and Dimension Jumps
MathematicsWe study the additive and fractal structure of digit-restricted subsets of the unit interval where AD=∑n=1∞anb−n:an∈D⊆{0,…,b−1},|D|≥2, defined by allowing only digits from D in base-b expansions.
