I am presently working on my undergraduate thesis in mathematics. My work consists mainly of analyzing a handful of sources, internalizing proofs and methods and then fleshing out the rough outline given to me by my advisor. To a large extent I am simply trying to grasp what was done in other sources, and then doing the same thing myself, adding my own twist.
How do I cite or refer to the sources I am using? In which places is it appropriate?
For instance, if I include a theorem from some source, internalize the proof strategy and then formulate a proof without peeking at the source, should I mention the source of the theorem?
I am now halfway done and have only 3 citations.
