| contents | We consider the Cauchy problem in the band $\mathbb{C}^{n}\times[0, T], n>1,T>0$, for a system of nonlinear differential equations structurally similar to the classical Navier-Stokes equations for an incompressible fluid. The main difference of this system is that it is generated not by the standard gradient operators $\nabla$, divergence div and rotor rot, but by the multidimensional Cauchy-Riemann operator $\overline{\partial}$ in $\mathbb{C}^{n}$, its formally adjoint operator $\overline{\partial}^{*}$ and the compatibility complex for $\overline{\partial}$, which is usually called the Dolbeault complex. The similarity of the structure makes it possible to prove for this problem the theorem of the existence of weak solutions and the open mapping theorem on the scale of specially constructed Bochner-Sobolev spaces. In addition, a criterion for the existence of a ``strong'' solution in these spaces is obtained. |
