Finite Fields, Characteristic and Algebraic Closure
Fields can be classified partly through characteristic and finite extensions. The source develops finite fields, adjoining polynomial roots, prime subfields and algebraic closure.

Products of fields have maximal ideals beyond coordinate kernels. Quotienting by such ideals produces ultraproducts, which transfer first-order algebraic statements and can crea…
