Abstract: I have proposed a mathematically rigorous definition of Coulomb branches of 3-dimensional supersymmetry gauge theories in March. It is not incarnated in full generality, but partially in the joint work with Braverman and Finkelberg. I now ask several questions on expected properties of Coulomb branches, especially in relation to the corresponding Higgs branches.
