Abstract

For a positive integer dd, the dd-dimensional Chebyshev-Frolov lattice is the Z\mathbb{Z}-lattice in Rd\mathbb{R}^d generated by the Vandermonde matrix associated to the roots of the dd-dimensional Chebyshev polynomial. It is important to enumerate the points from the Chebyshev-Frolov lattices in axis-parallel boxes when d=2nd = 2^n for a non-negative integer nn, since the points are used for the nodes of Frolov's cubature formula, which achieves the optimal rate of convergence for many spaces of functions with bounded mixed derivatives and compact support. The existing enumeration algorithm for such points by Kacwin, Oettershagen and Ullrich is efficient up to dimension d=16d=16. In this paper we suggest a new enumeration algorithm of such points for d=2nd=2^n, efficient up to d=32d=32.
