Convenient parameterizations of matrices in terms of vectors
M. Bruschi, F. Calogero
Convenient parameterizations of matrices in terms of vectors transform (certain classes of) matrix equations into covariant (hence rotation-invariant) vector equations. Certain rec…
Lower limit in semiclassical form for the number of bound states in a central potential
Fabian Brau, Francesco Calogero
We identify a class of potentials for which the semiclassical estimate of the number of (S-wave) bound states…
A class of (-dependent) potentials with the same number of (-wave) bound states
Fabian Brau, Francesco Calogero
We introduce and investigate the class of central potentials $$V_{\text{CIC}}(g^{2},μ^{2},\ell,R;r)=-\frac{g^{2}}{R^{2}} (\frac{r}{R})^{4\ell} {[ 1+(\frac{1}{2\ell+1}) (\frac{r}{R}…
Upper and lower limits on the number of bound states in a central potential
Fabian Brau, Francesco Calogero
In a recent paper new upper and lower limits were given, in the context of the Schrödinger or Klein-Gordon equations, for the number of S-wave bound states possessed by a m…
