Query: Pointwise estimates for Green's kernel of a mixed boundary value problem
  to the Stokes system in a polyhedral cone   The paper deals with a mixed boundary value problem for the Stokes system in
a polyhedral cone. Here different boundary conditions (in particular,
Dirichlet, Neumann, free surface conditions) are prescribed on the sides of the
polyhedron. The authors obtain regularity results for weak solutions in
weighted $L_2$ Sobolev spaces and prove point estimates of Green's matrix.
