This depends a lot on the branch of maths: eg topology has much more of a reputation for being wishy-washy than analysis. It also depends what the context is. A paper is not meant to prove things sufficiently for a layperson but for the author’s peers and so an omitted proof means one of “proven elsewhere;” “follows in a straightforward way from the definitions;” “follows in a straightforward way from an earlier proposition;” or “follows from a well-known pattern in the subfield.” And here “follows in a straightforward way” typically means something between “just look at;” “at each step there is only one reasonable thing to do so just do that;” and “apply all the standard tricks from the subfield and see what sticks.” It is not true that advanced mathematics is less rigorous than more elementary maths, it’s just that materials for advanced topics require more domain knowledge, and provide less hand-holding. |
