Analyticity properties of the Jost function for spheroidal potentials
The Jost function method is extended to study scattering phenomena produced by potentials having spheroidal symmetry. The spheroidal radial functions are constructed by taking the spherical wave functions as bases. The role of the Jost function in spherical potential scattering is reviewed. The …

Jost Functions for Jacobi Operators with Super-exponentially Decaying Parameters
… operator is related to the analyticity of the Jost function associated with J, which is in turn related to the spectral measure of J. Damanik and Simon demonstrated the equivalence between the exponential decay of these parameters and the analyticity of the Jost function on a disk whose radius …

Spectral points of the hypernuclear systems AAn and Ann
… describing the nn, n and interactions using the Jost functions method. The bound states for these three-body systems nn and n were sought as zeros of the corresponding three-body Jost function on the complex energy plane. Hypercentral potentials for corresponding systems are constructed from the …

Krein's identity and trace formulas for half-line Schrodinger operators
… $[0,\infty)$, where $V$ is a real-valued function integrable with respect to the weight $1+x$. The self-adjoint extensions are of Schr\"odinger-type and form a one-parameter family formally given by $H_{\alpha}=-d^2/dx^2+V$, $\alpha\in[0,\pi)$, with the boundary condition …

Topics in Electromagnetic, Acoustic, and Potential Scattering Theory
… (in which the velocity of propagation is a function only of the radial coordinate r. i.e.. <em>c</em> = <em>c</em>(<em>r</em>)) to a piecewise-uniform inhomogeneity. In Chapter 3 the Jost-function formulation of potential scattering theory is used to solve the radial differential equation …
