The Laplace-Beltrami Operator on the Surface of the Ellipsoid [PDF]
Symmetry, Integrability and Geometry: Methods and ApplicationsThe Laplace-Beltrami operator on (the surface of) a triaxial ellipsoid admits a sequence of real eigenvalues diverging to plus infinity. By introducing ellipsoidal coordinates, this eigenvalue problem for a partial differential operator is reduced to a two-parameter regular Sturm-Liouville problem involving ordinary differential operators.

Applications of a Laplace–Beltrami operator for Jack polynomials [PDF]
European Journal of Combinatorics, 2012 We use a new method to study the Laplace-Beltrami type operator on the Fock space of symmetric functions, and as an example of our explicit computation we show that the Jack symmetric functions are the only family of eigenvectors of the differential operator.

Laplace–Beltrami operators on noncommutative tori
Journal of Geometry and Physics, 2020 In this paper, we construct Laplace-Beltrami operators associated with arbitrary Riemannian metrics on noncommutative tori of any dimension. These operators enjoy the main properties of the Laplace-Beltrami operators on ordinary Riemannian manifolds. The construction takes into account the non-triviality of the group of modular automorphisms.

Statistical Properties of Eigenvalues of Laplace–Beltrami Operators [PDF]
Journal of Theoretical Probability, 2021 We study the eigenvalues of a Laplace-Beltrami operator defined on the set of the symmetric polynomials, where the eigenvalues are expressed in terms of partitions of integers. By assigning partitions with the restricted uniform measure, the restricted Jack measure, the uniform measure or the Plancherel measure, we prove that the global distribution of
