On a Metric on Translation Invariant Spaces
In this paper we de ne a metric on the collection of all translation invarinat spaces on a locally compact abelian group and we study some properties of the metric space.
متن کاملTranslation Invariant Operators on Hardy Spaces over Vilenkin Groups
We show that a number of well known multiplier theorems for Hardy spaces over Vilenkin groups follow immediately from a general condition on the kernel of the multiplier operator. In the compact case, this result shows that the multiplier theorems of Kitada [6], Tateoka [13], Daly-Phillips [2], and Simon [11] are best viewed as providing conditions on the partial sums of the Fourier-Vilenkin se...
متن کاملOn the two-wavelet localization operators on homogeneous spaces with relatively invariant measures
In the present paper, we introduce the two-wavelet localization operator for the square integrable representation of a homogeneous space with respect to a relatively invariant measure. We show that it is a bounded linear operator. We investigate some properties of the two-wavelet localization operator and show that it is a compact operator and is contained in a...
متن کاملNorms of Positive Operators on LP-Spaces
Let 0 < T: LP(Y, v) -+ Lq(X, ) be a positive linear operator and let HITIP ,q denote its operator norm. In this paper a method is given to compute 1Tllp, q exactly or to bound 11Tllp q from above. As an application the exact norm 11VIlp,q of the Volterra operator Vf(x) = fo f(t)dt is computed.
متن کاملNorms of Positive Operators on L-spaces
Let 0 ≤ T : L(Y, ν) → L(X,μ) be a positive linear operator and let ‖T‖p,q denote its operator norm. In this paper a method is given to compute ‖T‖p,q exactly or to bound ‖T‖p,q from above. As an application the exact norm ‖V ‖p,q of the Volterra operator V f(x) = ∫ x 0 f(t)dt is computed.
