Application of wavelets to singular integral scattering equations
B. M. Kessler, G. L. Payne, W. N. Polyzou
The use of orthonormal wavelet basis functions for solving singular integral scattering equations is investigated. It is shown that these basis functions lead to sparse matrix equa…
New Optimization Methods for Converging Perturbative Series with a Field Cutoff
B. Kessler, L. Li, Y. Meurice
We take advantage of the fact that in lambda phi ^4 problems a large field cutoff phi_max makes perturbative series converge toward values exponentially close to the exact values,…
Wavelets in Momentum-Space Scattering Calculations
B. M. Kessler, G. L. Payne, W. N. Polyzou
We demonstrate that wavelet bases have features that make them advantageous for solving momentum-space scattering integral equations. Using the example of two nucleons interacting…
Wavelet Notes
B. M. Kessler, G. L. Payne, W. N. Polyzou
Wavelets are a useful basis for constructing solutions of the integral and differential equations of scattering theory. Wavelet bases efficiently represent functions with smooth st…
Scattering Calculations with Wavelets
B. M. Kessler, G. L. Payne, W. N. Polyzou
We show that the use of wavelet bases for solving the momentum-space scattering integral equation leads to sparse matrices which can simplify the solution. Wavelet bases are applie…
