Help needed in understanding topology I am trying to understand basic principles of typology but am having a very hard time. I'm not good at maths at all (last studied it when I was 16) and I'm currently researching a PhD in literature and philosophy. My academic background is firmly situated in the humanities. The reason I ask about topology is that it seems to play a very important role in the philosophy of Gilles Deleuze, one of the key post-structuralist thinkers I'm writing about. I've looked over the wikipedia entry and got some very basic ideas from it, but I still found it very confusing for a non-mathematician such as myself to understand. If anyone would be able to explain some of the key ideas to me, or suggest places I can look for more info I would be very grateful!
