摘要：

Quasi-symmetry of a steady magnetic field means integrability of first-order guiding-center motion by a spatial symmetry. Here, we derive many restrictions on the possibilities for a quasi-symmetry. We also derive an analog of the Grad-Shafranov equation for the flux function in a quasi-symmetric magnetohydrostatic field.
