  The problem of two Aharonov-Bohm (AB) vortices for the Helmholtz equation is
examined in detail. It is demonstrated that the method proposed in [J. M.
Myers, J. Math. Phys. \textbf{6}, 1839 (1963)] for diffraction on a slit can be
generalized to get an explicit solution for AB vortices. Due to singular nature
of AB interaction the Green function and the scattering amplitude for two AB
vortices obey a series of partial differential equations. Coefficients entering
these equations, in their turn, fulfill ordinary non-linear differential
equations whose solutions can be obtained from a solution of the Painleve V (or
III) equation. The asymptotics of necessary functions for very large and very
small distances between two vortices are calculated explicitly. Taken together,
it means that the problem of two AB vortices is integrable.
