  The Lagrangian of the Liouville theory with topological defects is analyzed
in detail and general solution of the corresponding defect equations of motion
is found. We study the heavy and light semiclassical limits of the defect
two-point function found before via the bootstrap program. We show that the
heavy asymptotic limit is given by the exponential of the Liouville action with
defects, evaluated on the solutions with two singular points. We demonstrate
that the light asymptotic limit is given by the finite dimensional path
integral over solutions of the defect equations of motion with a vanishing
energy-momentum tensor.
