We present 3 open challenges in the field of Costas arrays. They are: a) the determination of the number of dots on the main diagonal of a Welch array, and especially the maximal ...
—We investigate the generalization of the Costas property in 3 or more dimensions, and we seek an appropriate definition. We offer a construction method based on the idea of res...
—We investigate the distance vectors contained in individual and in pairs of Costas arrays, and prove some rigorous results in the case of the algebraically constructed ones. Ove...
—The results of 2 experiments in Costas arrays are presented, for which theoretical explanation is still not available: the number of dots on the main diagonal of exponential Wel...
—Permutations of order N are generated using polynomials in a Galois field GF(q) where q > N+1, which can be written as a linear transformation on a vector of polynomial coeff...
