Re: Sheaves as a localisation of separated presheaves

" I realise I am basically talking to myself at this point but figure I should try to set the record straight!" Me too. But what I love are the ever so sparse instances of evidence to the contrary that come from unexpected quarters... ;) A big part of the problem is that there are fewer concepts than there are words for them. Unless you know every word for any given concept, you may not realize that someone is agreeing with you. Vaughan [For admin and other information see: http://www.mta.ca/~cat-dist/ ]
