摘要

We consider gamma-weighted anchored and ANOVA spaces of functions with mixed first order partial derivatives bounded in a weighted L-p, norm with 1 <= p <= infinity. The domain of the functions is D-d, where D subset of R is a bounded or unbounded interval. We provide conditions on the weights gamma that guarantee that anchored and ANOVA spaces are equal (as sets of functions) and have equivalent norms with equivalence constants uniformly or polynomially bounded in d. Moreover, we discuss applications of these results to integration and approximation of functions on D-d. (C) 2017 Elsevier Inc. All rights reserved.
