Cui, Xiao Na et al., A characterization of multidimensional multi-knot piecewise linear spectral sequence and its applications, Acta mathematica Sinica. English series (Print) , 29(9), 2013, pp. 1679-1690
We characterize a class of piecewise linear spectral sequences. Associated with the spectral sequence, we construct an orthonormal exponential bases for L 2([0, 1)d), which are called generalized Fourier bases. Moreover, we investigate the convergence of Bochner-Riesz means of the generalized Fourier series.
