Lattice field computations via recursive numerical integration
Tobias Hartung, Karl Jansen, Frances Y. Kuo +3
We investigate the application of efficient recursive numerical integration strategies to models in lattice gauge theory from quantum field theory. Given the coupling structure of…

Scaled lattice rules for integration on achieving higher-order convergence with error analysis in terms of orthogonal projections onto periodic spaces
Dirk Nuyens, Yuya Suzuki
We introduce a new method to approximate integrals which simply scales lattice rules from the unit cube $[0,1]^…
