For a nonconstant meromorphic function on the plane, let be its normalized pulled-back spherical area on , and the spherical length of its boundary image counted with multiplicity. The Cauchy-Schwarz inequality gives . If stayed above a positive constant for all large , integration of would make negative. Thus there are arbitrarily large radii with arbitrarily small, even when the total area is finite.
