H-型群的调和扩张分析
Analysis on harmonic extensions of H-type groups
摘要:
这篇博士论文的主题是H-型群的可解扩张上的调和分析。设N是H-型群,S=NA是N的秩为1的可解扩张.本文研究了S上适当的Hardy-Littlewood极大函数的弱1型有界性,并发展了S上的Calderon-Zygmund理论。然后应用前面的理论得到了S上一个特殊Laplacian的谱乘子的Mihlin-Hormander型定理。
英文摘要:
The subject of this PhD thesis is harmonic analysis on solvable extensions of H-type groups. Let N be an H-type group and S=NA be its solvable extension of rank one. The author study the weak type 1 boundedness of suitable Hardy-Littlewood maximal functions on S and develop a Calderon-Zygmund theory on S. The previous theory is then applied to obtain a Mihlin-Hormander type theorem for spectral multipliers of a distinguished Laplacian on S.
