  The electrostatic problem of two coaxial parallel charged disks of different
radii in infinite space is solved by expansion in terms of complex potentials.
For perfectly conducting disks a pair of coupled integral equations is derived
for the two weight functions of the expansion. The weight function on each disk
is linearly related to its radially symmetric charge density. If the radii are
equal and the disks are oppositely charged the pair of equations reduce to
Love's integral equation for the circular plate condenser.
