Non-extendable \(\mathbb{F}_{q}\)-Quadratic Perfect Nonlinear Maps



Let q be a power of an odd prime. We give examples of non-extendable \(\mathbb{F}_{q}\)-quadratic perfect nonlinear maps. We also show that many classes of \(\mathbb{F}_{q}\)-quadratic perfect nonlinear maps are extendable. We give a short survey of some related results and provide some open problems.
