3) Suppose X = Uier Ui, with each U₁ an open subset of X. If for each i E I, the subset U₁ is a Baire space for the induced topology on the subset U, C X, show that X itself is a Baire space. Assumption In the remaining part of this exercise, we assume that X is a space such that every point x EX has a neighborhood V in X which is a Baire space for the topology induced on the subset V CX.
