论文摘要
我们考虑具有分段恒定波数的异质介质中的声学散射。离散化是使用空间和runge-kutta卷积正交正交中的Galerkin边界元素方法进行的。我们证明了该方案的适当性，并提供了空间和时间收敛性的先验估计。
We consider acoustic scattering in heterogeneous media with piecewise constant wave number. The discretization is carried out using a Galerkin boundary element method in space and Runge-Kutta convolution quadrature in time. We prove well-posedness of the scheme and provide a priori estimates for the convergence in space and time.
