| Research Abstract |
We studied the Helmholtz equation, which is appeared in classical physics as wave equations, and in quantum mechanics as Schr\"odinger equations. We established the uniform resolvent estimate including the case of a two-dimensional, which is important in the scattering problem, corresponding as the application. In particular, in 2-D case, we find that we can compensate the term which remain negative term using the Hardy type inequalities related to radiation conditions. As a result, we can prove the uniform resolvent estimate in 2D case, which was already proved in $N(\geqq3)$ D case.
