View on Github →feat(NumberField): specialized version of Kummer Dedekind for the splitting of prime numbers (part 1) (#26137)
First part of the Kummer-Dedekind isomorphism for the splitting of rational prime numbers in number fields.
We define the exponent
of an algebraic integer θ
and define the isomorphism between (ℤ / pℤ)[X] / (minpoly θ)
and 𝓞 K / p(𝓞 K)
for primes p
which doesn't divide the exponent of θ
.
