Two-term spectral asymptotics for the Dirichlet pseudo-relativistic kinetic energy operator on a bounded domain

Sebastian Gottwald

Continuing the series of works following Weyl's one-term asymptotic formula for the counting function $N(\lambda )={\sum }_{n=1}^{\infty }({\lambda }_n-\lambda {)}_{-}$ of the eigenvalues of the Dirichlet Laplac…
