Asymptotic behavior of the solution of the Neumann problem with a delta-like boundary function
A. A. Ershov Chelyabinsk State University, ul. Brat'ev Kashirinukh 129, Chelyabinsk, 454136 Russia
Abstract:
A uniform asymptotic expansion is found for the integral $\iint_S\nabla^2 u\, dx\,dy$, where $u$ is the solution of the Neumann problem with a delta-function-like derivative on the boundary. A physics application of the result is discussed.
Key words:
Laplace equation, asymptotic expansion of an integral related to the Neumann problem, delta-function-like derivative.
