Abstract
In this paper a representation formula for solutions of the equation ( ) DELTAu + 2Ke(u) = 0, K a constant, in a punctured disc in terms of multi-valued meromorphic functions is found. As application it is dedu ced that a necessary and sufficient condition for a solution of (), K > 0, being asymptotic radially symmetric is integral e(u) < infinity.
