I have a few questions about the references in a PhD thesis in mathematics:
- What would be a "normal" range of items there? I am not sure if there is only a few items in the reference it may not be suitable. Would 30 be good? 50? Or 100?
- Is there any conventional way to order the references?
- When I add a paper to the reference, do I really need to read the paper? For example, I may read from some other paper that "the following result was proved in [1]". Then can I also add [1] to my reference by writing "the following result was proved in [1]", without really reading [1]? It is possible that [1] may be too long/tedious/difficult to read, difficult to find, or not in English, etc.
