Hayk Nersisyan

摘要:

本文研究了三维不可压Euler方程组的控制系统。我们表明,速度场和压力的流体是完全可控的投影由相同的有限维控制。此外,速度近似可控。我们还证明了有限维外力不能精确控制三维Euler系统。

英文摘要:

In this paper, we study the control system associated with the incompressible 3D Euler system. We show that the velocity field and pressure of the fluid are exactly controllable in projections by the same finite-dimensional control. Moreover, the velocity is approximately controllable. We also prove that 3D Euler system is not exactly controllable by a finite-dimensional external force.
