The covariance kernel of this Gaussian measure is a product of univariate kernels and satisfies some special properties. We study $(s, t)$-weak tractability of this multivariate problem, and obtain a necessary and sufficient condition for $s>0$ and $t\\in(0,1)$. Our result can apply to the problems with covariance kernels corresponding to Euler and Wiener integrated processes, Korobov kernels, and analytic Korobov kernels.", "revisions": [ { "version": "v1", "updated": "2018-02-06T07:41:05.000Z" } ], "analyses": { "subjects": [ "41A25", "41A63", "65D15", "65Y20" ], "keywords": [ "non-homogenous tensor product problems", "weak tractability", "average case", "covariance kernel", "analytic korobov kernels" ], "note": { "typesetting": "TeX", "pages": 20, "language": "en", "license": "arXiv", "status": "editable" } } }
