Generic properties of the Laplace spectrum and eigenfunctions
Oliver Fürst, Eva-Maria Hekkelman, Malte Leimbach
We prove that the spectrum of the Laplace--Beltrami operator on compact Riemannian manifolds without boundary is generically linearly independent over . Furthermore, we…
Operator systems and positive extensions over discrete groups
Evgenios T. A. Kakariadis, Malte Leimbach, Ivan G. Todorov +1
The extension problem asks whether positive semi-definite functions on a symmetric unital subset of a discrete group can be extended to positive semi-definite functions on the whol…
Convergence of Peter--Weyl Truncations of Compact Quantum Groups
Malte Leimbach
We consider a coamenable compact quantum group as a compact quantum metric space if its function algebra is equipped with a Lip-norm. By using…
Gromov--Hausdorff Convergence of Spectral Truncations for Tori
Malte Leimbach, Walter D. van Suijlekom
We consider operator systems associated to spectral truncations of tori. We show that their state spaces, when equipped with the Connes distance function, converge in the Gromov--H…
