Let $\Omega\subset\mathbb R^d$ be a domain, let $\beta$ be a Robin boundary parameter, and let $\gamma$ be the Riesz-mean order. Theorem gives a two-term semiclassical asymptotic e…

Let $N_{\sigma,\tau}(\beta,\lambda)$ denote the shifted lattice-point counting function and let $R^\gamma_{-1/2}(\beta,\lambda)$ denote the corresponding Riesz mean for the harmoni…
