More generally, the number d(a, b) = ∣ a − b is the distance between the points a and b. It follows easily from Proposition 1.4.2 that d(x, y) ≥ 0, and d(x, y ... Webb9 feb. 2024 · Indeed, if ψ is a field homomorphism, in particular it is a ring homomorphism. Note that the kernel of a ring homomorphism is an ideal and a field F only has two ideals, namely {0}, F. Moreover, by the definition of field homomorphism, ψ ⁢ (1) = 1, hence 1 is not in the kernel of the map, so the kernel must be equal to {0}. ∎ jimmy\u0027s new castle pa
