Perturbations of the Haar wavelet [PDF]

open access: yesProceedings of the American Mathematical Society, 1997
Summary: Let \(m \in Z^+\) be given. For any \(\varepsilon > 0\) we construct a function \(f^{\{\varepsilon \}}\) having the following properties: (a) \(f^{\{\varepsilon \}}\) has support in \([-\varepsilon , 1 + \varepsilon ]\). (b) \(f^{\{\varepsilon \}} \in C^m(-\infty , \infty)\).
