Abstract
We charactyerize the fibre-faithful maps in TOP:the category of T1-spaces and contionuous functions are exactly the maps f:X-->Y such that every injective restrction f/X':X'-->f[X'], X'<=X and f/X' injective, is a homeomorphism. Categorically this is equivalent to say that a special diagram is a pulback.File in questo prodotto:
