Walsh - Fourier Coefficients and Locally Constant Functions
A condition on the Walsh-Fourier coefficients of a continuous function/ sufficient to conclude that/is locally constant is obtained. The condition contains certain conditions identified earlier by Boikarev, Coury, Skvorcov and Wade, and Powell and Wade.
متن کاملRepresentation of Functions as Absolutely Convergent Fourier-stieltjes Transforms
0. Introduction. Let G be a locally compact Abelian group, and G* its group of (continuous) characters. We write (y, x) to indicate the function on G*XG which is the value of the character y EG* at the point *6G, or, dually, the value of the character xEG at the point y EG*. Borel sets in G are taken to be the smallest cr-algebra of sets containing all closed sets. We consider the set of all re...
متن کاملFourier Coefficients of Mathieu Functions Stable Regions *
Continued fraction expansions for the eigenvalues A= A(I', h2 ) and for the Fourier coefficients c~n/co are given by Tamir and Wang in [2]. These relations are valid both in the s table (I' real) and unstable (I' complex) regions . F (I') == C~,.1Co is numerically evaluated and depicted. It is seen from the graphs in [2] that the given formulas for C~,JCO are not particularly suitable for numer...
متن کاملSPECTRUM OF THE FOURIER-STIELTJES ALGEBRA OF A SEMIGROUP
For a unital foundation topological *-semigroup S whose representations separate points of S, we show that the spectrum of the Fourier-Stieltjes algebra B(S) is a compact semitopological semigroup. We also calculate B(S) for several examples of S.
متن کامل(Non-)amenability of Fourier and Fourier–Stieltjes algebras
Let G be a locally compact group. We show that its Fourier algebra A(G) is amenable if and only if G has an abelian subgroup of finite index, and that its Fourier– Stieltjes algebra B(G) is amenable if and only if G has a compact, abelian subgroup of finite index.
