摘要

针对具有描述各向异性介质动力学特性的严格双曲型二阶方程组的非平稳边值问题,提出了边界积分方程的求解方法。用广义函数法在不同维数的广义向量函数空间中构造它们的解。得到了这些系统的格林张量和基于它的新的基本张量来构造高斯、基尔霍夫和格林公式的动态类比。构造了包括激波在内的BVP的广义解。利用积分核的性质,构造了求解BVP的奇异边界积分方程。证明了BVP解的唯一性。

Singular Boundary Integral Equations of Boundary Value Problems for Hyperbolic Equations of Mathematical Physics
The method of boundary integral equations is developed for solving the nonstationary boundary value problems (BVP) for strictly hyperbolic systems of second-order equations, which are characteristic for description of anisotropic media dynamics. The generalized functions method is used for the construction of their solutions in spaces of generalized vector functions of different dimensions. The Green tensors of these systems and new fundamental tensors, based on it, are obtained to construct the dynamic analogues of Gauss, Kirchhoff, and Green formulas. The generalized solution of BVP has been constructed, including shock waves. Using the properties of integrals kernels, the singular boundary integral equations are constructed which resolve BVP. The uniqueness of BVP solution has been proved.
