WebbTake A = K[X], B = K[X, Y] / (XY) and α the following application A = K[X] ⊂ K[X, Y] → K[X, Y] / (XY) = B. Obviously α is injective. Write B = K[x, y] with xy = 0. Let Q = xB. It is obvious that Q is prime ( B / Q ≅ K[Y]) and P = α − 1(Q) = XA. Now choose X 1 ∈ AP and observe that α(X 1) = x 1. But x 1 = 0 1 in BQ because yx = 0 and y ∈ B − Q. WebbIn Mathematics, a bijective function is also known as bijection or one-to-one correspondence function.
