On the generalized potential problem for a surface of revolution [PDF]

Proceedings of the American Mathematical Society, 1984
The following generalized potential problem is considered: given an arbitrary potential distribution on a surface of revolution, the charge density is to be determined. The problem is called generalized due to the assumption that the point charge potential diminishes with the distance R R as R

Quantum particle on a surface: Catenary surface and paraboloid of revolution

Physica Scripta, 2021
Abstract We revisit the Schrödinger equation of a quantum particle that is confined on a curved surface. Inspired by the seminal work of da Costa (1980 Phys. Rev. A 23 1982) we find the field equation in a more convenient notation. The
