On generalized Hadamard matrices GH(q,q)'s and GH(q,q^2)'s
A matrix is a generalized Hadamard matrix of order
with entries from which is a finite group of order (for short
) such that whenever the set
contains each element of
exactly times. In this paper, we construct 's
and 's over additive groups of finite fields
's by using some sorts of functions
On a class of -Bernoulli, -Euler and -Genocchi polynomials
The main purpose of this paper is to introduce and investigate a class of
-Bernoulli, -Euler and -Genocchi polynomials. The -analogues of
well-known formulas are derived. The -analogue of the Srivastava--Pint\'er
addition theorem is obtained. Some new identities involving -polynomials are
proved
On Q-derived polynomials
It is known that Q-derived univariate polynomials (polynomials defined over Q, with the property that they and all their derivatives have all their roots in Q) can be completely classified subject to two conjectures: that no quartic with four distinct roots is Q-derived, and that no quintic with a triple root and two other distinct roots is Q-derived. We prove the second of these conjectures
