WebDec 10, 2016 · 1 Answer Sorted by: 2 HINT: If X has the discrete topology, every function from X to Y is continuous, and every subset of X is both open and closed. If you choose Y so that it has a subset that isn’t open and a subset that isn’t closed, it’s not hard to get your first example. (You can even take Y to be X with a different topology.) floor tiles kitchen b\u0026q

WebProve that F [ x] is the integral closure of A. My Proof: Since we have x = x 3 / x 2, the field of fractions of A is F ( x), because x 2, x 3 ∈ A. Also, x ∈ F ( x) is a root of t 2 − x 2 ∈ A [ t], so A is not integrally closed. In fact, F [ x] is generated by 1, x as an A -module, so any element of F [ x] is integral over A.
