The Noun project has icons for very diverse topics, so it may be helpful in general. Their science and math category does seem not to cover the specific concepts you mention, but some of the available ones may be useful as inspiration.

Hello,

Seeking for icons to reprent things like "axioms", "theorems" and so on for the french wikiversity, I found the "Project Nuvola 2.0+"[1], despite it seems that there's currently not much activity on it, I began to put new proposals on the page. I think I red some messages on this list about this topic. Is there some active projects I should look at?

By the way, if you have ideas to illustrate the following concepts, let me know:
Axiom
Corollary
Definition
Example
Lemma
Principle
Proof
Property
Suggestion
Theorem

You may look at [2] to see my current proposals for some of them.
