A residue theorem for Malcev–Neumann series [PDF]
Advances in Applied Mathematics, 2005 In this paper, we establish a residue theorem for Malcev-Neumann series that requires few constraints, and includes previously known combinatorial residue theorems as special cases. Our residue theorem identifies the residues of two formal series that are related by a change of variables.

Mitigating quantum errors via truncated Neumann series
Science China Information Sciences, 2021 Quantum gates and measurements on quantum hardware are inevitably subject to hardware imperfections that lead to quantum errors. Mitigating such unavoidable errors is crucial to explore the power of quantum hardware better.

Incorporating reflection boundary conditions in the Neumann series radiative transport equation: application to photon propagation and reconstruction in diffuse optical imaging. [PDF]
Biomed Opt Express, 2018 We propose a formalism to incorporate boundary conditions in a Neumann-series-based radiative transport equation. The formalism accurately models the reflection of photons at the tissue-external medium interface using Fresnel's equations.

Convergence of iterative methods based on Neumann series for composite materials: Theory and practice [PDF]
, 2017 Iterative fast Fourier transform methods are useful for calculating the fields in composite materials and their macroscopic response. By iterating back and forth until convergence, the differential constraints are satisfied in Fourier space and the ...

On the matrix inversion approximation based on neumann series in massive MIMO systems [PDF]
2015 IEEE International Conference on Communications (ICC), 2015 Zero-Forcing (ZF) has been considered as one of the potential practical precoding and detection method for massive MIMO systems. One of the most important advantages of massive MIMO is the capability of supporting a large number of users in the same time-

Second Type Neumann Series of Generalized Nicholson Function
Results in Mathematics, 2019 The second type Neumann series are considered whose building blocks are generalized Nicholson's functions B_\nu^p(x) = J_\nu^p(x)+ Y_\nu^p(x), being J_\nu, Y_\nu Bessel functions of the first and second kind of order \nu, p \geq 2 integer. Closed form definite integral expressions are obtained for such series with the aid of the associated Dirichlet ...

ANALYTIC DISCRETE-ORDINATES SOLUTION FOR TIME-DEPENDENT TRANSPORT IN FINITE MEDIA [PDF]
EPJ Web of Conferences, 2021 We present an extension of the Analytic Discrete-Ordinates method to time-dependent transport in finite media. The application of this technique to time-dependent transport is primarily accomplished through the use of a Laplace transform.
