Abstract: | We consider a Cauchy-type boundary-value problem, a problem with three boundary conditions, and the Dirichlet problem for
a general typeless fourth-order differential equation with constant complex coefficients and nonzero right-hand side in a
bounded domain Ω ⊂ R
2 with smooth boundary. By the method of the Green formula, the theory of extensions of differential operators, and the theory
of L-traces (i.e., traces associated with the differential operation L), we establish necessary and sufficient (for elliptic operators) conditions of the solvability of each of these problems
in the space H
m
(Ω), m ≥ 4. |
