WebSome aspects of the convergence of the Born series have been considered by Jost and Pais 2) and by Kohn 3). Kohn has treated the case of nonrelativistic scattering by a spherically symmetric static potential and has examined the convergence of the Born series for each partial wave, both for tan ql and for St = eli'h, where q1 is the usual phase ...

The Born series is the expansion of different scattering quantities in quantum scattering theory in the powers of the interaction potential (more precisely in powers of where is the free particle Green's operator). It is closely related to Born approximation, which is the first order term of the Born series. The series can formally be understood as power series introducing the coupling constant by substitution . The speed of convergence and radius of convergence of the Born series are related to WebWe benchmark wavefields, which are computed in several 3D large-scale subsurface models with a sparse multifrontal direct solver and the nonadaptive/adaptive stencils, against analytical solutions when available and the highly accurate discretization-free convergent Born series method. WebIf a series is uniformly convergent in [a, b] and the individual terms are continuous, 1. The series sum is also continuous. 2. The series may be integrated term by term.
