鞅Hardy空间上的有界算子

Bounded operators on Martingale Hardy spaces

Giorgi Tutberidze

摘要:

我的论文的目的是讨论,发展和应用这个迷人的理论连接到现代调和分析的最新发展。特别地,我们研究了Vilenkin-傅里叶级数部分和的一些强收敛结果。此外,我们还得到了费耶平均连续模范数收敛的充要条件.此外,我们考虑Riesz和Nörlund对数平均。并证明了这些结果在特殊意义下是最好的。作为应用,指出了一些著名的和新的结果。此外,我们研究了一些$T$的手段,这是“逆”求和方法的Nörlund,但只有在这种情况下,当他们的系数是单调的。

英文摘要:

The aim of my thesis is to discuss, develop and apply the newest developments of this fascinating theory connected to modern harmonic analysis. In particular, we investigate some strong convergence result of partial sums of Vilenkin-Fourier series. Moreover, we derive necessary and sufficient conditions for the modulus of continuity so that norm convergence of subsequences of Fejér means is valid. Furthermore, we consider Riesz and Nörlund logarithmic means. It is also proved that these results are the best possible in a special sense. As applications both some well-known and new results are pointed out. In addition, we investigate some $T$ means, which are "inverse" summability methods of Nörlund, but only in the case when their coefficients are monotone.
