| Research Abstract |
We study on the relation between APN (Almost Perfect Non-linear) functions, which are investigated in the field of cryptography, and dual hyperovals. Using this relation, we construct new dual hyperovals. Next, using semifields, we construct many new dual hyperovals. Moreover, we also construct many new non isomorphic quotients of the Veronesean dual hyperoval, and the Buratti Del Fra dual hyperoval in small dimensional projective spaces.
