The property of a system of partial differential equations with variable coefficients to belong to one or another homotopic type depends on the domain point at which this system is considered. The degeneration manifolds split the original region into parts. The study of the influence of such degeneration on the solvability character of the boundary value problems is important.

We consider the system of $n$ partial second order differential equations

with a real function $$L(x), $x\; =\; (x$₁, ¼ ,x_n).

We obtain the conditions, under which the modified Dirichlet problem for this system is solvable up to an arbitrary harmonic function of $n-1$ variables.
