在本节中,我们介绍了一些符号,给出了单层和双层势的一些性质,并讨论了求解格林公式引起的外边值问题(0.20)的积分方程。这个讨论是研究这个问题(0.20)的可解性的初步步骤。经典的方法导致积分方程不总是可解的。因此,我们希望推导出一些无条件可解的积分方程来求解(0.20),这些方程等价于边值问题(0.20)。
In this section we introduce some notations, formulate some properties of the potentials of the single and double layers, and discuss the integral equations for solving the exterior boundary value problem (0.20) resulting from Green’s formula. This discussion is a preliminary step in a study of the solvability of the problem (0.20). The classical approach leads to integral equations which are not always solvable for somek. Therefore one wishes to derive some unconditionally solvable integral equations for solving (0.20), equations which are equivalent to the boundary value problem (0.20).
