On Hardy's Theorem on SU(1,1)

Chinese Annals of Mathematics,Series B 2007年第4期28卷 429-440页

The classical Hardy theorem asserts that f and its Fourier transform f can not both be very rapidly decreasing. This theorem was generalized on Lie groups and also for the Fourier-Jacobi transform. However, on SU（1, 1） there are infinitely many “good” functions in the sense that f and its spherical Fourier transform y both have good decay. In this paper, we shall characterize such functions on SU（1, 1）.

H^1-ESTIMATES OF LITTLEWOOD-PALEY AND LUSIN FUNCTIONS FOR JACOBI ANALYSIS

Analysis in Theory and Applications 2009年第3期25卷 201-229页

作者： takeshi Kawazoe Department of Mathematics Keio University at Fujisawa 5322 endo FujisawaKanagawa 252-8520 Japan

For a ≥β≥ -1/2 let △（x） = （2shx）^2α＋1 （2chx）2β＋1 denote the weight function on R＋ and L^1 （△） the space of integrable functions on R＋ with respect to △（x）dx, equipped with a convolution structure. For a suitable Ф ∈ L^1 （△）, we put Фt（x） = t^-1 △（x）^-1 △（x/t）Ф（x/t） for t 〉 0 and define the radial maximal operator MФ, as usual manner. We introduce a real Hardy space H^1 （△） as the set of all locally integrable functions f on R＋ whose radial maximal function MФ （f） belongs to L^1 （△）. In this paper we obtain a relation between H^1 （△） and H^1 （R）. Indeed, we characterize H^1 （△） in terms of weighted H^1 Hardy spaces on R via the Abel transform of f. As applications of H^1 （△） and its characterization, we shall consider （H^1 （△）,L^1 （△））-boundedness of some operators associated to the Poisson kernel for Jacobi analysis： the Poisson maximal operator Me, the Littlewood-Paley g-function and the Lusin area function S. They are bounded on L^p（△） for p 〉 1, but not true for p = 1. Instead, Mp, g and a modified Sa,r are bounded from H^1 （△） to L^1 （△）.

H^1-Estimates of the Littlewood-Paley and Lusin Functions for Jacobi Analysis Ⅱ

引用

Analysis in Theory and Applications 2016年第1期32卷 38-51页

作者： takeshi Kawazoe Department of Mathematics Keio University at SFC Endo Fujisawa Kanagawa252-8520 Japan

Abstract. Let （R＋,＊,A） be the Jacobi hypergroup. We introduce analogues of the Littlewood-Paley g function and the Lusin area function for the Jacobi hypergroup and consider their （H^1, L^1 ） boundedness. Although the g operator for （R＋,＊,A） possesses better property than the classical g operator, the Lusin area operator has an obstacle arisen from a second convolution. Hence, in order to obtain the （H^1,L^1） estimate for the Lusin area operator, a slight modification in its form is required.

AIM To unravel relationships between gastrointestinal(GI)symptoms impairing quality of life(QOL)and clinical profiles of diabetes mellitus(DM)patients. METHODS We enrolled 134 outpatients with type 2 *** age was 64.7 years,mean body mass index was 24.7 RESULTS Lower abdominal symptoms were found to be more frequent than those affecting the upper *** duration and medications showed associations with GI *** identified differences in peak prevalences of the five ***(P=0.02vs 10-14 years)and total GI symptoms(P=0.01 and P=0.02 vs 5-9 years and 10-14 years,respectively)peaked at a diabetes duration of 15-19 ***(P=0.004)and postprandial fullness(P=0.03)tended to increase with disease *** and diarrhea showed bimodal peaks,with the first early and the second late(e.g.,P=0.03 at 15-19 years vs 10-14years for diarrhea)in the disease ***,GI symptoms showed clustering that reflected the region of the GI tract affected,i.e.,constipation and diarrhea had similar frequencies(P<0.0001). CONCLUSION Our study highlights the importance of questioning patients about QOL impairment due to abdominal symptoms,especially in the early and the late periods of diabetes.
