Abstract

Our purpose in this paper is to classify the non-topological solutions of equations

$ -\Delta u +\frac{4e^u}{1+e^u} = 4\pi\sum\limits_{i = 1}^k n_i\delta_{p_i}-4\pi\sum^l\limits_{j = 1}m_j\delta_{q_j} \quad{\rm in}\;\; \mathbb{R}^2,\;\;\;\;\;\;(E) $

where $ \{\delta_{p_i}\}_{i = 1}^k $ (resp. $ \{\delta_{q_j}\}_{j = 1}^l $) are Dirac masses concentrated at the points $ \{p_i\}_{i = 1}^k $, (resp. $ \{q_j\}_{j = 1}^l $), $ n_i $ and $ m_j $ are positive integers. Denote $ N = \sum^k_{i = 1}n_i $ and $ M = \sum^l_{j = 1}m_j $ satisfying that $ N-M>1 $.

Problem $ (E) $ arises from gauged sigma models and we first construct an extremal non-topological solution $ u $ of $ (E) $ with asymptotic behavior

$ u(x) = -2\ln |x|-2\ln\ln|x|+O(1)\quad{\rm as}\quad |x|\to+\infty $

and with total magnetic flux $ 4\pi (N-M-1) $. And then we do the classification for non-topological solutions of $ (E) $ with finite magnetic flux. This solves a challenging long standing problem. We believe that our approach is novel and applies to other types of equations.
