New developments in convergence of wavelet expansion of functions Lᴾ (R²), Sobolev space Hˢ (R²) and Lᴾ (S²)

In this work, we highlight to some methods that can develop the convergence of wavelet expansions under some new forms of partial sums operators. We improve some requirements on classical wavelet expansions on R² domain. In addition, it is interesting to consider the spherical wavelets which are def...
