I asked a question related to my current thesis on MathOverflow and got there a really helpful answer by Iosif Pinelis. Obviously, I want to cite his answer. Is it enough to put something like the following sentence at the beginning of the proof's chapter?
The following proof based on ideas given by Iosif Pinelis in a proof on mathoverflow.net [1]
([1]
points to the reference of Pinelis' answer in the bibliography of my thesis)
Do I need to cite Pinelis' answer whenever I use a notation/an idea from his post (it might be hard to tell afterwards, which are my original ideas and which ideas come from his post)?
