✦ Synopsis

We present several naturally defined σ-ideals which have Borel bases but, unlike for the classical examples, these ideals are not of bounded Borel complexity. We investigate set-theoretic properties of such σ-ideals.

Constructing normal bases of \(G F\left(q^{n}\right)\) over \(G F(q)\) can be done by probabilistic methods as well as deterministic ones. In the following paper we consider only deterministic constructions. As far as we know, the best complexity for probabilistic algorithms is \(O\left(n^{2} \log ^
