Boundary Perturbations of Steklov Eigenvalues
Lihan Wang
We consider the dependence of non-zero Steklov eigenvalues on smooth perturbations of the domain boundary. We prove that these eigenvalues are generically simple under such boundar…

Upper bound of the counting function of Steklov eigenvalues
Fei He, Lihan Wang
We study the counting function of Steklov eigenvalues on compact manifolds with boundary and obtain its upper bound involving the leading term of Weyl's law. Our estimate can be vi…
