Spectral structure of the Neumann--Poincaré operator on tori
Kazunori Ando, Yong-Gwan Ji, Hyeonbae Kang +2
We address the question whether there is a three-dimensional bounded domain such that the Neumann--Poincaré operator defined on its boundary has infinitely many negative eigenvalue…

A concavity condition for existence of a negative Neumann-Poincaré eigenvalue in three dimensions
Yong-Gwan Ji, Hyeonbae Kang
It is proved that if a bounded domain in three dimensions satisfies a certain concavity condition, then the Neumann-Poincaré operator on the boundary of the domain or its inversion…

The first Hadamard variation of Neumann-Poincaré eigenvalues on the sphere
Kazunori Ando, Hyeonbae Kang, Yoshihisa Miyanishi +1
The Neumann-Poincaré operator on the sphere has , , as its eigenvalues and the corresponding multiplicity is . We consider the bifurcation…
