A note on Kuttler-Sigillito's inequalities

Asma Hassannezhad, Anna Siffert

We provide several inequalities between eigenvalues of some classical eigenvalue problems on domains with $C^{2}$ boundary in complete Riemannian manifolds. A key tool in the proof i…

Alexandrov Spaces with Integral Current Structure

Maree Jaramillo, Raquel Perales, Priyanka Rajan +2

We endow each closed, orientable Alexandrov space $(X, d)$ with an integral current $T$ of weight equal to 1, $\partial T = 0 an d {(} T) = X$ , in other words, we prove that $(X, d…

Existence of metrics maximizing the first eigenvalue on non-orientable surfaces

Henrik Matthiesen, Anna Siffert

We prove the existence of metrics maximizing the first eigenvalue normalized by area on closed, non-orientable surfaces assuming two spectral gap conditions. These spectral gap con…
