Abstract: I’ve frequently heard the assertion that “hyperkahler manifolds are self-mirror up to rotation.” I’m not so sure this is true in general, but I know one example of such a variety: multiplicative hypertoric varieties; these are what happens when you cut up a real torus into polytopes, and then send the polytopes to have a toric hyperkahler party. I’ll discuss recent work with Gammage and McBreen showing that self-homological homological mirror symmetry after rotation holds in this case and do my best to show how this fits in with a larger story of K-theoretic Coulomb branches.
