Invariants of Quadratic Forms and applications in Design Theory
Oliver W. Gnilke, Padraig O Cathain, Oktay Olmez +1
The study of regular incidence structures such as projective planes and symmetric block designs is a well established topic in discrete mathematics. Work of Bruck, Ryser and Chowla…

On the norms of r-circulant matrices with generalized bi-periodic Fibonacci numbers
Mehmet Dagli, Elif Tan, Oktay Olmez
In this paper, we give upper and lower bounds for the spectral norms of r-circulant matrices with the generalized bi-periodic Fibonacci numbers. Moreover, we investigate the eigenv…

Some families of directed strongly regular graphs obtained from certain finite incidence structures
Oktay Olmez, Sung Y. Song
This is the second report of our work on the construction of directed strongly regular graphs. In our previous work, we constructed a couple of infinite families of new directed st…
