Characterization of the Eigenvalues and Eigenfunctions of the Helmholtz Newtonian operator N^k
Zhe Wang, Ahcene Ghandriche, Jijun Liu
The Newtonian potential operator for the Helmholtz equation, which is represented by the volume integral with fundamental solution as kernel function, is of great importance for di…
