The dynamics of the motion of a viscous liquid film on a flat hard surface is investigated. The regularity of the solution of the Poisson equation in the region formed by the intersection of the areas under the integer angles is proved. We prove some existence and regularity results for fourth-order elliptic equations. Research of boundary value problems with fractional derivatives is presented.
