Construction of Difference Sets from Unions of Cyclotomic Classes of Order N=14
Let G be an additive group of order v, D be a non-empty proper k-subset of G, and λ be any integer. Then D is a (v, k, λ) - difference set if every nonzero element of the group can be expressed as a difference d1 - d2 of elements of D in exactly

Let \(G\) be a group not necessary abelian, and \(N\) a normal subgroup of \( G\). Suppose there is a \((v,k,\lambda)\)-DS in \(G\). Bounds on \(| N| \) and \(\lambda\) are given in terms mainly of \(k-\lambda\) under (strong) assumptions on the structure and the order of \(G/N\) using group rings.

Supplementary difference sets and optimal designs [PDF]
D-optimal designs of order n = 2 v ≡ 2 (mod 4), where q is a prime power and v = q2 + q + 1 are constructed using two methods, one with supplementary difference sets and the other using projective planes more directly.An infinite family of Hadamard ...

Difference Equations and Julia Sets of Several Functions for Degenerate q-Sigmoid Polynomials
In this article, we construct a new type of degenerate q-sigmoid (DQS) polynomial for sigmoid functions containing quantum numbers and find several difference equations related to it.

The difference vectors for convex sets and a resolution of the geometry conjecture
The geometry conjecture, which was posed nearly a quarter of a century ago, states that the fixed point set of the composition of projectors onto nonempty closed convex sets in Hilbert space is actually equal to the intersection of certain translations ...
