Abstract |
The paper is devoted to investigation of nonlocal boundary value problem for a differential-operator equation
with the nonlinear right part and with the operator B=(B1,…,Bp), where
Bj≡zj∂∂zj, j=1,…,p, --- operators of the generalized differentiation on complex variable zj. This problem is incorrect in the Hadamard sense and its sobvability related to the small denominators. By using of the Nash-Mozer iteration scheme the conditions of the sobvability of the problem in the scale of spaces of functions of several complex variables are established.
