Some Problems of Self-Adjoint Extension in the Schrodinger equation
T. Nadareishvili, A. Khelashvili
The Self-Adjoint Extension in the Schrodinger equation for potentials behaved as an attractive inverse square at the origin is critically reviewed. Original results are also presen…

Coulomb Potential and Witten Superalgebra
Anzor Khelashvili, Tamar Khachidze
The additional hidden symmetry of the Coulomb-Kepler problem is reviewed in classical as well as in quantum mechanics. The main purpose is to elucidate the role of this kind of sym…

On the nature of "hidden symmetry" or "accidental degeneracy" in the Kepler problem
Tamar T. Khachidze, Anzor A. Khelashvili
We propose a symmetry of the Dirac equation under the interchange of signs of eigenvalues of the Dirac's operator. We show that the only potential which obeys this requirement…
