Abstract

I will review an elegant, theory-independent argument that proves the existence of exactly marginal operators in the presence of a conformal manifold. The proof relies on a few technical assumptions, which I will discuss in detail. The rest of the discussion will be phrased in terms of conformal interfaces separating two CFTs on the conformal manifold, which we take as an opportunity to discuss the fundamentals of defect CFTs. The overarching topic into which this result fits is that of proving certain (AdS) swampland conjectures from CFT principles.

Short Stories 1

You know those annoying social media films where a mic is shoved in front of a bunch of students and they're asked questions that have nothing to do with their studies or their lives, hoping they say something vaguely funny or interesting that might get a billion views on TikTok?

Short Stories 2

It's tough, isn't? Probably one of the biggest challenges for mathematicians of all ages. Just how do you talk about your subject to friends and family who aren't mathematical? Our crack team of undergraduates ponder.

Doncha love AI!! So clever! Does all your work in, like, one nanosecond! It's, like, your bestie!!
 
Doncha hate AI?? Thinks it's so clever! But you can't trust it!
