Ring theory question … Maybe question topology. (Not sure)?
Suppose P homomorphism: R -> S. I came across a posting on here talking about function. f *: Spec (R) -> Spec (S). a * f (p) means that f ^ (-1) (p) in this talk with his teacher said that as soon as this map. Continuously between Spec (R). And Spec (S) because we know that only a perfect image before key
Failure to comply "immediately". To A = Spec (R) B = Spec (S). The first thing you write the wrong map : A φ *: Spec (S) -> Spec (R). Now X_r = A – V (r) by at r ∈ R and V (r) = p (in particular | R r ∈ p). you like to φ. * ^ (-1) (X_r) = X_φ (r) from the R X_r basis for topoloy of Spec () and you will continue. Must have a picture before the opening will open. . Φ Now * ^ (-1) (X_r) = B – φ * ^ (-1) (V (r)) = B – / φ (* ^ (-1) (p |) r ∈ p. , p only ideal. R) = B – / (q key | φ * S (q) = p) = B – / (q key. S | φ ^ (-1) (q) = p) = B – / p φ () = X_φ (r) Steve.

Rings of Continuous Functions (Graduate Texts in Mathematics) $59.95 The objective of this book is the systematic study of the ring of all real valued continuous functions on arbitrary topological spaces. Great emphasis is placed on the study of ideals, and on the associated residue class rings. Questions of extending continuous functions from a subspace to the entire space arise as a necessary adjunct and are dealt with in considerable detail. Many problems provid… |
