Resumen:
We analyze the application of the ?tridiagonal representation approach? (TRA) to the Schrödinger equation for some simple, exactly solvable,quantum-mechanical models. In the case of the Kratzer?Fues potential, the expression for the energy does not appear to be correct. Inaddition, the well known Frobenius method, which resembles the TRA, is far simpler, clearer, and more elegant, in addition to giving thecorrect result.
