An Idea to Compute DtN Maps of PDE with Constant Coefficients
Consider the following problem related to an ordinary differential equation: ‘For given constans ua,ub,M,N, function f(x) in [a,b], find ∂u/∂n at x = a,b which satisfies u″+Mu′+Nu = f in (a,b), u(a) = ua,u(b) = ub.’ This kind of problem is called the “Dirichlet‐Neumann map problem”. This problem is usually …
