Abstract:
We study the existence of a boundary trace for minorized solutions of the equation
u + K ( x ) e2u = 0 in the unit open ball B2 of R2. We prove that this trace is an outer regular Borel measure on
B2, not necessarily a Radon measure. We give sufficient conditions on Borel measures on
B2 so that they are the boundary trace of a solution of the above equation. We also give boundary removability results in terms of generalized Bessel capacities.
