OP here. Thanks for taking time to reply. Really thank you.
Obviously I know very little about these areas and that is why I posted such a question. By posing this question, I didn't mean that I wanted to 'get there' quickly. In fact I am in no hurry and willing to go as deep as possible.
What I actually mean to ask is that I was looking for a kind of syllabus/crash courses so that I can get an idea about what kind of mathematics is involved in these areas. Based on that, I'll be able to start my studies in much more organized way. Also, from there on, I myself be able to figure out how to look for further resources. This is the style of learning I usually follow.

Hope you understand my point.
