Monte Carlo cubature construction
S Hayakawa - Japan Journal of Industrial and Applied Mathematics, 2021 - Springer
In numerical integration, cubature methods are effective, especially when the integrands can
be well-approximated by known test functions, such as polynomials. However, the …

Quasi-Monte Carlo integration on manifolds with mapped low-discrepancy points and greedy minimal Riesz s-energy points
S De Marchi, G Elefante - Applied Numerical Mathematics, 2018 - Elsevier
In this paper we consider two sets of points for Quasi-Monte Carlo integration on two-
dimensional manifolds. The first is the set of mapped low-discrepancy sequence by a …

Monte Carlo methods on compact complex manifolds using Bergman kernels
T Lemoine, R Bardenet - arXiv preprint arXiv:2405.09203, 2024 - arxiv.org
In this paper, we propose a new randomized method for numerical integration on a compact
complex manifold with respect to a continuous volume form. Taking for quadrature nodes a …
