dc.description.abstract | Since Horadam and de Launey introduced the cocyclic framework on combinatorial designs
in the 1990s, it has revealed itself as a powerful technique for looking for (cocyclic) Hadamard matrices.
Ten years later, the series of papers by Kotsireas, Koukouvinos and Seberry about Hadamard
matrices with one or two circulant cores introduced a different structured approach to the Hadamard
conjecture. This paper is built on both strengths, so that Hadamard matrices with cocyclic cores are introduced
and studied. They are proved to strictly include usual Hadamard matrices with one and two
circulant cores, and therefore provide a wiser uniform approach to a structured Hadamard conjecture. | es |
