A counterexample to the Drury permanent conjecture

George Hutchinson (2017)

Special Matrices

Similarity:

We offer a counterexample to a conjecture concerning the permanent of positive semidefinite matrices. The counterexample is a 4 × 4 complex correlation matrix.

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.
