Query: On Boundary Perturbations in Liouville Theory and Brane Dynamics in
  Noncritical String Theories   We study certain relevant boundary perturbations of Liouville theory and
discuss implications of our results for the brane dynamics in noncritical
string theories. Our results include
  (i) There exist monodromies in the parameter $\mu_{\rm B}$ of the
Neumann-type boundary condition that create an admixture represented by the
Dirichlet type boundary condition.
  (ii) Certain renormalization group flows can be studied perturbatively, which
allows one to determine the results of the corresponding brane decays.
  (iii) There exists a simple renormalization group flow that can be calculated
exactly. In all the cases that we have studied, the RG flow acts like a
covering transformation for the mondromies mentioned under (i).
