The Hydrogenic Atom. We consider now a special case of the hydrogenic atom in dimension d = 3, that is to say a Schrodinger operator given by H = -([d.sup.2]/[dr.sup.2]) + U(r), with U(r) as in (11) and V(r) = -([e.sup.2]/r).
If we compare the harmonic oscillator H = -[DELTA] + [r.sup.2] with the hydrogenic atom H = -[delta] - 1/r in three dimensions we see two very different systems from the point of view of stability and the spatial distribution of the respective wave functions.
For the hydrogenic atom its radial wave function 1/r [g.sub.nl] depends of the principal (n) and orbital (l) quantum numbers, which are associated to eigenvalues for energy and angular momentum, respectively.
His topics include from solar systems to atoms, interpretation of the quantum rules, non-relativistic hydrogenic atoms with spin, the primary supersymmetry of the Dirac equation, and a different extension of the solution space.
In between he offers chapters on matrix groups, Lie algebras, matrix algebras, operator algebras, EXPonentiation, structure theory for Lie algebras, root spaces and Dynkin diagrams, real forms, Riemannian symmetric spaces, contraction, hydrogenic atoms, and Maxwell's equations.
