15 صفحه اولBASIC PROPERTIES OF LINEAR RELATIVE n-WIDTHS
The paper examines the basic properties of linear relative widths as well as the different ways of finding their estimates. AMS Subject Classification: 41A35, 41A29
متن کاملBEST APPROXIMATION SETS IN -n-NORMED SPACE CORRESPONDING TO INTUITIONISTIC FUZZY n-NORMED LINEAR SPACE
The aim of this paper is to present the new and interesting notionof ascending family of $alpha $−n-norms corresponding to an intuitionistic fuzzy nnormedlinear space. The notion of best aproximation sets in an $alpha $−n-normedspace corresponding to an intuitionistic fuzzy n-normed linear space is alsodefined and several related results are obtained.
متن کاملMatrices and n-Widths
This paper is concerned with a collection of ideas and problems in approximation theory which lead to some solved and unsolved problems in matrix theory. As an example, consider the problem of approximating the identity matrix by matrices of fixed rank where the norm is taken to be the maximum of the absolute value of the elements of the matrix. This problem is unsolved.
متن کاملLinear Formulas in Continuous Logic
We prove that continuous sentences preserved by the ultramean construction (a generalization of the ultraproduct construction) are exactly those sentences which are approximated by linear sentences. Continuous sentences preserved by linear elementary equivalence are exactly those sentences which are approximated in the Riesz space generated by linear sentences. Also, characterizations for linea...
