Weak Type Estimates for Square Functions of Dunkl Heat Flows (2101.04056v2)
Published 7 Jan 2021 in math.CA, math.AP, and math.PR
Abstract: The weak $(1,1)$ boundedness of the Littlewood--Paley--Stein square function for the Dunkl heat flow is proved via estimates on the Dunkl heat kernel of integral type and the Caldr\'{o}n--Zygmund decomposition, which is the continuity of the recently work [arXiv:2003.11843] where the dimension-free $Lp$ boundedness of the same square function is studied.
