Martin Gugat, Vincent Perrollaz, Lionel Rosier

摘要:

研究了具有透明边界条件的拟线性双曲型方程组在小源项存在时解的长时间行为。即使系统的有限时间稳定性不被保存,它在这里示出的指数收敛到稳定状态仍然持有与衰减率是成比例的对数的源项的振幅。结果表明,系统的动力学边界条件,以处理初始数据是免费的任何兼容性条件。

英文摘要:

We investigate the long-time behavior of solutions of quasilinear hyperbolic systems with transparent boundary conditions when small source terms are incorporated in the system. Even if the finite-time stability of the system is not preserved, it is shown here that an exponential convergence towards the steady state still holds with a decay rate which is proportional to the logarithm of the amplitude of the source term. The result is stated for a system with dynamical boundary conditions in order to deal with initial data that are free of any compatibility condition.
