I am now writing my graduate thesis, it includes some basics mathematical theorems/propositions.

I got a trouble in writing, more concretely, I do not know when can I state a mathematical claim as a theorem/proposition.

So what is the difference between a proposition and a theorem? When can I state a mathematical claim as a theorem and as a proposition?

I beg your pardon for my stupid question. Please help me. Thanks

Choosing which results should be labeled theorem and which results should be labeled proposition or lemma is probably part of the work you need to do when writing your thesis.

I suggest you reserve theorem for the really important results that you want to highlight, even if you don't prove them in the text.
