Pro tip : sometimes, the title of maths paper happen to use words you know. Like "complex", "linear", "category", "group", "ring", "foliation" or whatever. But it usuelly means something totally different than what you would expect.

I'd say yes. Many haven't even heard of the difference between Ichneumonidae and Braconidae! (What are schools teaching nowadays etc grumble mumble 😎) More seriously, I find most people haven't really heard of them, let alone be familiar with the concept.
