题目：Boundedness of composition operators associated with different homogeneities on H?lder spaces
报告人： Prof. Yongsheng Han, Auburn University
摘要: An initial impetus for the study of composition of operators of different types came from the study of the problems in complex analysis. More precisely, these questions arise when one combines the standard operators with those operators that appear in the study of some sub-elliptic estimates, and on strongly pseudo-convex domains. In this talk, we introduce a new class of H?lder spaces associated with different homogeneities and characterize these spaces via the Littlewood-Paley theory. We describe that the composition of two Calderón-Zygmund singular integral operators with different homogeneities is bounded on these new H?lder spaces.
