Matrix Inversion Method for Integral Equations with Kernels Containing Poles ”
An interpolative technique is presented which yields accurate numerical solutions to various types of linear integral equations, the kernels of which contain poles. It is also shown that two techniques which are successful when the kernel is weakly singular’are unsatisfactory when the singularities are poles, The approaches discussed for the various equations are illustrated by example, (Submit...
متن کاملMatrix Rational Interpolation with Poles as Interpolation Points
In this paper, we show the equivalence between matrix rational interpolation problems with poles as interpolation points and no-pole problems. This equivalence provides an effective method for computing matrix rational interpolants having poles as interpolation points. However, this equivalence is only valid in those cases where enough pole information is known. It is an open problem on how one...
متن کاملExceptional points and double poles of the S matrix.
Exceptional points and double poles of the S matrix are both characterized by the coalescence of a pair of eigenvalues. In the first case, the coalescence causes a defect of the Hilbert space. In the second case, this is not so as shown in previous papers. Mathematically, the reason for this difference is the biorthogonality of the eigenfunctions of a non-Hermitian operator that is ignored in t...
متن کاملS - matrix and R - matrix determination of the low - energy 5 He and 5 Li resonance parameters
We study the low-energy 3/2 and 1/2 states of 5He and 5Li in a microscopic cluster model. The scattering phase shifts of Bond (α + n) and of Schwandt (α + p), respectively, are reproduced well. We determine the resonance parameters by localizing the poles of the analytically continued S-matrix at complex energies. Our results differ from conventional R-matrix resonance parameters, which were ex...
متن کاملS - matrix versus R - matrix determination of the low - energy 5 He and 5 Li resonance parameters
We study the low-energy 3/2 and 1/2 states of 5He and 5Li in a microscopic cluster model. The scattering phase shifts of Bond (α + n) and of Schwandt (α + p), respectively, are reproduced well. We determine the resonance parameters by localizing the poles of the analytically continued S-matrix at complex energies. Our results are in conflict with conventional R-matrix resonance parameters, but ...
