论文摘要
我们在开放式套装$ \ frac12 \,\ log(-ulog(-Δ)$的离散光谱中,我们获得了光谱不平等和渐近公式。我们还得出了有关特征值$λ_1(ω)$的下限的一些结果,并将其与以前已知的不等式进行了比较。
We obtain spectral inequalities and asymptotic formulae for the discrete spectrum of the operator $\frac12\, \log(-Δ)$ in an open set $Ω\in\Bbb R^d$, $d\ge2$, of finite measure with Dirichlet boundary conditions. We also derive some results regarding lower bounds for the eigenvalue $λ_1(Ω)$ and compare them with previously known inequalities.
