I am writing a math thesis.
I want to provide a result in chapter 2, but formally prove this result in chapter 8. This is because I am introducing a bunch of definitions in between these chapters and they cannot be moved in front of or within chapter 2.
Can I say something like, “as we will see in chapter 8, this result in chapter 2 is true”? In other words, can you allude to the proof of a result that will be given only later in the thesis?
I don’t feel like it is good practice because it sorts of destroys the “surprise factor”, and it also makes the reader jump 100 pages to see the result. How should I handle this?
