Subbasis topology
WebThe product topology on Πn∈I Xn is the topology generated by the subbasis A which consists of all sets of the form πn−1 [Un ] where πn is the projection of Πm∈I Xm onto Xn and Un ∈ τ (Xn ). f 3 To better visualize what the open sets of this topology look like, let I = ω, where ω is the first inductive ordinal. WebThen (i) If e N is spanned by a subbasis of N, then there is an isomorphism φ: X Σ,N ∼ = X Σ, e N × T N/ e N ∼ = X Σ, e N × (C *) n-k, where the last line follows simply from the definition of an algebraic torus. (ii) Let N 0 ⊆ N be a sublattice …
