## Non-commuative geometry and its prerequisites [closed]

I am specifically looking forward to study NCG from Connes's book.What are the absolute prerequisites needed

There is a good discussion of such issues avail on MO; please expand your question a bit, otherwise it is too open-ended. – S. Sra May 21 2012 at 16:09
Good working knowledge in (algebraic) topology, (differential) geometry and (quantum) physics... – BY May 21 2012 at 16:17
I forgot Operator Algebras... – BY May 21 2012 at 16:18
From what I experienced, you should rather read a few pages for getting an idea, what a specific topic and its ncg analogue is about, and then look at the references/search the web. The book seemed fairly sketchy at my level, but provides often the big picture. From what I was told, some fairly well-known people are doing research, which is motivated partly by understanding/explaining a few pages from this book to a wider audience. – Marc Palm May 21 2012 at 17:06
As Mrc Plm says, this is not really a book that one can study from. Rather it is useful for getting the big picture about NCG. That said, I am voting to close - this question is not specific enough. – MTS May 21 2012 at 17:24

$C^\ast$-algebra would be a good place to start. Afterwards, you can learn $K$-theory of $C^\ast$-algebras.
