We define a family of quaternary sequences over the residue class ring modulo 4 of length
pq, a product of two distinct odd primes, using the generalized cyclotomic classes modulo pq …

EN=(e1, e2,···, eN)∈ AN, where A={a1, a2,···, ak},(k∈ N, k≥ 2) is a finite set of k symbols.
Bérczi estimated the pseudorandom measures for a truly random sequence EN of k symbol …

In a series of papers Mauduit and Sárközy introduced and studied pseudorandom measures
of finite sequences of $ k $ symbols. In this paper we construct a large family of …

In 2002 Mauduit and Sárközy started to study finite sequences of $ k $ symbols\begin
{document} $ E_ {N}=\left (e_ {1}, e_ {2},\cdots, e_ {N}\right)\in\mathcal {A}^{N}, $\end …

Cyclotomic sequences have good cryptographic properties and are closely related to
difference sets. This paper proposes a new class of binary generalized cyclotomic …

By using finite fields of order p^ r pr with r ≥ 2 r≥ 2 and their quadratic characters, Sárközy
and Winterhof presented a construction for binary sequences of length p^ r pr with strong …
