Ideals

**Abstract:**

This paper deals with wavelet frames in anisotropic Besov spaces $B_{pq}^{s,a}(\mathbb{R}^n)$,
$s\in\mathbb{R}$, $0<p,q\leq\infty$, and $a=(a_1,\dots,a_n)$ is an anisotropy,
with $a_i>0$, $i=1,\dots,n$, $a_1+ \cdots + a_n=n$. We present sub-atomic and
wavelet decompositions for a large class of distributions. To some extent our
results can be regarded as anisotropic counterparts of those recently obtained
by H. Triebel in 2003.

**Keywords:**

Anisotropic function spaces, sub-atomic decomposition, wavelet decomposition,
wavelet frames.
