Green functions for powers of the Laplace-Beltrami operator.
It is shown that, in contrast to the usual biharmonic Green function, the Green function for the biharmonic Laplace-Beltrami operator on any complete Riemannian manifold is of constant sign. Some further details are given for the ca...

PT-Symmetric Laplace-Beltrami Operator in the Strip on a Sphere
Numerical analysis indicates that all eigenvalues of a PT-symmetric Laplace-Beltrami operator in the strip on a sphere are real. However, a complete proof is not known....

Higher Laplace–Beltrami operators on bounded symmetric domains
It was conjectured by the first author and Peetre that the higher Laplace–Beltrami operators generate the whole ring of invariant operators on bounded symmetric domains. We give a proof of the conjecture for domains of rank...

Prolongation of symmetric Killing tensors and commuting symmetries of the Laplace operator
We determine the space of commuting sym- metries of the Laplace operator on pseudo-Riemannian man- ifolds of constant curvature and derive its algebra structure. Our construction is based on Riemannian tractor calculus, allowing us ...
