asymptoticbehavior of Jost functions near resonance points for WignerVonneumann type potentials
(AIP Publishing, 199101)In this work are considered radial Schrodinger operators  psi" + V(r)psi = Epsi, where V(r) = a sin br/r + W(r) with W(r) bounded, W(r) = O(r2) at infinity (a,b real). The asymptotic behavior of the Jost function and ... 
exact behavior of Jost functions at lowenergy
(AIP Publishing, 198801)For Schrödinger operators with central potential q(r) and angular momentuml, the behavior of the Jost function F l (k) as k→0 is investigated. It is assumed that ∫∞ 0 d r (1+r)σ‖q(r)‖<∞, where σ≥1. Situations where q is ...
