Partial Difference Sets with Paley Parameters
نویسندگان
چکیده
Partial difference sets with parameters (v,k,k,/x) = (v,(v— l)/2,(v — 5)/4,(v— l)/4) are called Paley partial difference sets. By using finite local rings, we construct a family of Paley PDSs for abelian/7-groups with any given exponent. Furthermore, we prove some non-existence results on Paley PDSs. Using these results, we prove that Paley PDSs exist in a rank 2 abelian group if and only if the group is isomorphic to Zpr x Zpr where p is an odd prime.

Paley type partial difference sets in non p-groups
By modifying a construction for Hadamard (Menon) difference sets we construct two infinite families of negative Latin square type partial difference sets in groups of the form Z3 × Zp where p is any odd prime. One of these families has the wellknown Paley parameters, which had previously only been constructed in p-groups. This provides new constructions of Hadamard matrices and implies the exis...
متن کاملPseudo-Paley graphs and skew Hadamard difference sets from presemifields
Let (K,+, ∗) be an odd order presemifield with commutative multiplication. We show that the set of nonzero squares of (K, ∗) is a skewHadamard difference set or a Paley type partial difference set in (K,+) according as q is congruent to 3modulo 4 or q is congruent to 1 modulo 4. Applying this result to the Coulter–Matthews presemifield and the Ding–Yuan variation of it, we recover a recent cons...
متن کاملPaley Type Group Schemes from Cyclotomic Classes and Arasu-dillon-player Difference Sets
In this paper, we present constructions of abelian Paley type group schemes by using multiplicative characters of finite fields and Arasu-Dillon-Player difference sets. The constructions produce many new Paley type group schemes that were previous unknown in our classification of Paley type group schemes in finite fields of small orders.
متن کاملA family of skew Hadamard difference sets
In 1933 a family of skew Hadamard difference sets was described by Paley using matrix language and was called the Paley–Hadamard difference sets in the literature. During the last 70 years, no new skew Hadamard difference sets were found. It was conjectured that there are no further examples of skew Hadamard difference sets. This conjecture was proved to be true for the cyclic case in 1954, and...
متن کاملInequivalence of Skew Hadamard Difference Sets and Triple Intersection Numbers Modulo a Prime
Recently, Feng and Xiang [10] found a new construction of skew Hadamard difference sets in elementary abelian groups. In this paper, we introduce a new invariant for equivalence of skew Hadamard difference sets, namely triple intersection numbers modulo a prime, and discuss inequivalence between Feng-Xiang skew Hadamard difference sets and the Paley difference sets. As a consequence, we show th...
