  We show that for the Green's function on an area-minimizing boundary, it is
bounded below universally by the Euclidean Green's function. We also obtain
asymptotics of the Green's function near the pole and infinity. These are done
by proving a $C^\alpha$ convergence of the Green's functions under the
convergence of area-minimizing boundaries. For converging multiplicity 1
stationary varifolds, we have $L^p$ convergence of the Green's functions, but
there are examples of stationary varifolds on which the lower bounds and
asymptotics may fail. An application of the lower bound will be given in [9].
