Query: On the construction of the correlation numbers in Minimal Liouville
  Gravity   The computation of the correlation numbers in Minimal Liouville Gravity
involves an integration over moduli spaces of complex curves. There are two
independent approaches to the calculation: the direct one, based on the CFT
methods and Liouville higher equations of motion, and the alternative one,
motivated by discrete description of 2D gravity and based on the Douglas string
equation. However these two approaches give rise to the results that are not
always consistent among themselves. In this paper we explore this problem. We
show that in order to reconcile two methods the so-called discrete terms in the
operator product expansion in the underlying Liouville theory must be properly
taken into account. In this way we propose modified version of the expression
for four-point correlation number and find full agreement between direct and
alternative approaches. Our result allows to consider correlators without any
restrictions on the number of conformal blocks contributing to the matter
sector correlation function.
