 Why this easy to state, well-defined computation has these meanings?
+===== ring objects =====
+I was diverted to watch Nakajima's talk, and also reading the paper on non-cotangent type Coulomb branch.
+It was nice to get some pictures. The general setup should be like, $G$ acts Hamiltonianly on some variety $M$ (affine?), then there should be some mirror dual variety $M^\vee$ with $G^\vee$ action.
+The Whittaker reduction of $M^\vee$ by $G^\vee$ should be the desired Coulomb branch.
+How do we get $M^\vee$? Well, that's not important. The important thing is to construct a ring object. I don't know the general philosophy.
+Anyway, that's not relevant for this paper.
