... basis

In general, the thresholding procedure can be applied to any basis for the signal decomposition (e.g. Mallat 1998).

Lipschitz exponents are also called Hölder exponents in the mathematical literature (Dremin et al. 2001; Mallat 1998).

... wavelet

In most cases, discrete wavelets cannot be represented by an analytical expression or by the solution of some differential equation, and instead are given numerically as solutions of functional equations (e.g. Mallat 1998).
