When writing a mathematical journal or thesis, where is the best place to put the background material like theorems and definitions?
Currently I am thinking of two options:
1) Place it in a separate section on its own
2) Put the theorems/definitions individually at the start of each appropriate section.
For example, let's say in the paper Theorem 1 to 10, and Definition 1 to 10 are needed. (These Theorems are known results from books/other papers.)
Should I:
1) Put all the above in one section (e.g. after the introduction).
2) Put them in the relevant sections just as they are about to be used.
Thanks for any tips.
