Frames associated with expansive matrix dilations.

Kwok-Pun Ho (2003)

Collectanea Mathematica

Similarity:

We construct wavelet-type frames associated with the expansive matrix dilation on the Anisotropic Triebel-Lizorkin spaces. We also show the a.e. convergence of the frame expansion which includes multi-wavelet expansion as a special case.

A note on the matrix Haffian.

Heinz Neudecker (2000)

Qüestiió

Similarity:

This note contains a transparent presentation of the matrix Haffian. A basic theorem links this matrix and the differential ofthe matrix function under investigation, viz ∇F(X) and dF(X). Frequent use is being made of matrix derivatives as developed by Magnus and Neudecker.
