Product Invariant Piecewise Polynomial Approximations of Signals
نویسنده
چکیده
The Strang and Fix conditions relate the accuracy of a finite element method to its ability to reproduce polynomials. A similar condition is proved to exist for the approximation of the product on these finite elements. Piecewise polynomial approximations are studied further, including a constructive description of all related approximate product operators.

In recent years wavelet have had an important impact on signal processing theory and practice. The eeectiveness of wavelets is mainly due to their capability of representing piecewise smooth signals with few non-zero coeecients. Away from discontinuities, the inner product between a wavelet (with a number of zero moments) and a smooth function will be either zero or very small. 8 At singular po...
متن کاملWidth invariant approximation of fuzzy numbers
In this paper, we consider the width invariant trapezoidal and triangularapproximations of fuzzy numbers. The presented methods avoid the effortful computation of Karush-Kuhn-Tucker Theorem. Some properties of the new approximation methods are presented and the applicability of the methods is illustrated by examples. In addition, we show that the proposed approximations of fuzzy numbers preserv...

While abstract interpretation is not theoretically restricted to specific kinds of properties, it is, in practice, mainly developed to compute linear over-approximations of reachable sets, aka. the collecting semantics of the program. The verification of user-provided properties is not easily compatible with the usual forward fixpoint computation using numerical abstract domains. We propose her...
