We consider algorithms that use finitely many continuous linear functionals. We use a unified method to investigate tractability of the above multivariate problems, and obtain necessary and sufficient conditions for strong polynomial tractability, polynomial tractability, quasi-polynomial tractability, uniformly weak tractability, $(s,t)$-weak tractability, and weak tractability. Our results can apply to multivariate approximation problems with kernels corresponding to Euler kernels, Wiener kernels, Korobov kernels, Gaussian kernels, and analytic Korobov kernels.", "revisions": [ { "version": "v1", "updated": "2019-01-17T12:17:39.000Z" } ], "analyses": { "subjects": [ "41A63", "65D15", "65Y20" ], "keywords": [ "non-homogeneous tensor product problems", "worst case setting", "weak tractability", "multivariate linear tensor product problems", "study multivariate linear tensor product" ], "note": { "typesetting": "TeX", "pages": 23, "language": "en", "license": "arXiv", "status": "editable" } } }
