In wavelet theory smootheness is one of the main interests. By the Mallat-Meyer construction (see [He] or [Ne]) the problem of finding smooth wavelets is reduce
Based on a representation lemma. Riesz type kernels on the local field K and on the integer ring O in K are coitstructed. Furthermore, we discuss approximation
In this paper we investigate the asymptotic bebaviour of μ-average n-widths of integral operator Kon the Wiener space. where K is the inverse operator of an or
