Abstract:

We study a Grad-Shafranov type equations, describing in dimension N = 2 the equilibrium configurations of a plasma in a Tokamak. First we establish some uniqueness results which is sharp in 2d and new in higher dimensions. Then we discuss the spike analysis of the singular limits, giving a converse results of the existence results by Flucher-Wei. We will also talk about some recent progress on the 2D spike analysis. This is based on joint work with A. Jevnikar and D. Bartolucci.
