On real-valued homomorphisms in countably generated differential structures

Differential completions and compactifications of a differential space

“…Then C does not posses the spectral property. It is a contradiction with Theorem 1 and Corollary 6 from the work [3] (see also Theorem 2.3 (Twierdzenie 2.3) and Corollary 2.6 (Wniosek 2.6) from [2]). COROLLARY 4.1 Let X be a topological Hausdorff space.…”
