some properties of fuzzy hilbert spaces and norm of operators
in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...
15 صفحه اولRemarks on some interpolation spaces
One purpose of this paper is to introduce a new idea of associating microlocal measures to bounded functions of bounded variation, and even to functions in the interpolation space (H(Q)yL (Q))1.7oo, in order to replace and improve some methods from geometric measure theory. Some properties of similar interpolation spaces are reviewed first. I do not remember when I met Enrico MAGENES for the fi...

Throughout this paper x"'), x-"1 ,. . ., x~,' will denote the roots of the n-th Chebyshev polynomial T " (x) [T " (cosh) = cos nJ]. f(x) will denote a function continuous in [-1, +1] and L,(f(x)) will denote the Lagrange interpolation polynomial of f(x) taken at the points xi(") (i = 1, 2,. . ., n) ; in other words, L,(f(x)) is a polynomial of degree not greater than (n-1) for which') L " (f(x+...
متن کاملSome Remarks on Multilinear Maps and Interpolation
A multilinear version of the Boyd interpolation theorem is proved in the context of quasi-normed rearrangement-invariant spaces. A multilinear Marcinkiewicz interpolation theorem is obtained as a corollary. Several applications are given, including estimates for bilinear fractional integrals.
متن کاملSome Remarks on Minimal Spline Interpolation
Interpolation of 2n+k data by spline spaces of order k with n knots is studied. Some conditions on existence of interpolating splines are given. Numerical methods for constructing a solution are suggested. Mathematics Subject Classification: 41A05, 41A15
