abstract:
Both the domains $D^{+}$ and $D^{-}$ are considered, where the third and the
fourth problems are formulated. Green's formulas are written and by means them
uniqueness theorems are proved for the third and fourth problems. For the third
and fourth problems, in the domains $D^{+}$ and $D^{-}$ Fredholm integral
equations are derived and existence theorem are proved.
