摘要：
The following minimax problem is studied for functions u that are harmonic in the unit disc and vanish in m points (zi): to render the minimum of // Del u/////u// a maximum with respect to the location of the points z i. The authors treat both the cases of u vanishing exactly at the given points and u approximately vanishing. The problem is related to an extrapolation problem for harmonic functions.
