Fast arithmetic for the algebraic closure of finite fields
Luca De Feo, Javad Doliskani, Éric Schost · 2014
We present algorithms to construct and do arithmetic operations in the algebraic closure of the finite field Fp. Our approach is inspired by algorithms for constructing irreducible polynomials, which first reduce to prime power degrees, then use composita techniques. We use similar ideas to give efficient algorithms for embeddings and isomorphisms.
