چکیده
An S-set in the circle group T is a closed subset S of T for which j(S) — k(S). We construct a non-S-set S satisfying _ U LiP„(Dn k(S)cj(S). o>0 Thus Lipa(T) n A(T) is not a big enough part of A{T) to test the synthesizability of a given closed subset of T.

Some Results on Convex Spectral Functions: I
In this paper, we give a fundamental convexity preserving for spectral functions. Indeed, we investigate infimal convolution, Moreau envelope and proximal average for convex spectral functions, and show that this properties are inherited from the properties of its corresponding convex function. This results have many applications in Applied Mathematics such as semi-definite programmings and eng...
متن کاملPolynomial Functions and Spectral Synthesis on Abelian Groups
Spectral synthesis deals with the description of translation invariant function spaces. It turns out that the basic building blocks of this description are the exponential monomials, which are built up from exponential functions and polynomial functions. The author collaborated with Laczkovich [Math. Proc. Cambridge Philos. Soc. 143 (2007), no. 1, 103–120] proved that spectral synthesis holds o...
متن کاملSpectral Techniques in the Reversible Logic Circuit Synthesis of Switching Functions
ABSTRACT This paper reviews the recent developments in the use of reversible expansions and reversible spectral transforms in the reversible logic circuit design of binary and multiple-valued switching functions. Since Shannon and Davio expansions are two basic expansions in the general Reed-Muller families of expansions that play an essential role in the spectral-based design of logic circuits...
متن کاملOn Spectral Synthesis in Several Variables
In a recent paper we proposed a possible generalization of L. Schwartz’s classical spectral synthesis result for continuous functions in several variables. The idea is based on Gelfand pairs and spherical functions while “translation invariance” is replaced by invariance with respect to the action of affine groups. In this paper we describe the function classes which play the role of the expone...
متن کاملError bounds in approximating n-time differentiable functions of self-adjoint operators in Hilbert spaces via a Taylor's type expansion
On utilizing the spectral representation of selfadjoint operators in Hilbert spaces, some error bounds in approximating $n$-time differentiable functions of selfadjoint operators in Hilbert Spaces via a Taylor's type expansion are given.
