Definition | df-sfl1 32887* |
Temporary construction for the splitting field of a polynomial. The
inputs are a field 𝑟 and a polynomial 𝑝 that we
want to split,
along with a tuple 𝑗 in the same format as the output.
The output
is a tuple 〈𝑆, 𝐹〉 where 𝑆 is the splitting field
and 𝐹
is an injective homomorphism from the original field 𝑟.
The function works by repeatedly finding the smallest monic irreducible factor, and extending the field by that factor using the polyFld construction. We keep track of a total order in each of the splitting fields so that we can pick an element definably without needing global choice. (Contributed by Mario Carneiro, 2-Dec-2014.) |
