Classical Goppa codesLet us recall that in (4.4) a.code was defined as the set of words (., ., ... , .) ∈ . such that . + .(β.) + .(β.). + ... + .(β.). = 0 where ß is a primitive . root of unity and 1 ≤ . < .. Here d is the designed distance. We can rewrite this as follows: . i.e.

Elementary concepts from algebraic geometryLet k be an algebraically closed field. We denote by a.. or simply by A. the n-dimensional affine space over k. It carries a topology, the Zariski-topology whose closed sets are the sets of zeroes of ideals a of k: V(a) = {(x.,...,x.) ∈ A.: f(x.,...,x.) = 0 for all f ∈ a}.
