Zhang, Hai Ying et al., An Affirmative Result of the Open Question on Determining Function Jumps by Spline Wavelets, Acta mathematica Sinica. English series (Print) , 34(5), 2018, pp. 921-932
We study the open question on determination of jumps for functions raised by Shi and Hu in 2009. An affirmative answer is given for the case that spline-wavelet series are used to approximate the functions.
