Abstract :
This paper investigate the mutlifractal properties of the sunspot time series. The results obtained by us provide positive evidence regarding the existence of mutlifractality in the sunspot time series. In detail, we find the partition function is convex up, which indicate the time series is mutlifractal. And then, we calculate the width, maximum of the singular spectrum and the results are also show mutlifractality exist in the time series.
