New theoretical insights in the decomposition and time-frequency representation of nonstationary signals: the IMFogram algorithm
Antonio Cicone, Wing Suet Li, Haomin Zhou
The analysis of the time-frequency content of a signal is a classical problem in signal processing, with a broad number of applications in real life. Many different approaches have…
Time-frequency representation of nonstationary signals: the IMFogram
Philippe Barbe, Antonio Cicone, Wing Suet Li +1
Iterative filtering methods were introduced around 2010 to improve definitions and measurements of structural features in signal processing. Like many applied techniques, they pres…
The enumeration of extreme rigid honeycombs
Hari Bercovici, Wing Suet Li
Rigid tree honeycombs were introduced by Knutson, Tao, and Woodward and they were shown by Dykema, Collins, Timotin, and the authors to be sums of extreme rigid honeycombs, with un…
Intersection theory and the Horn inequalities for invariant subspaces
Hari Bercovici, Wing Suet Li
We provide a direct, intersection theoretic, argument that the Jordan models of an operator of class C_{0}, of its restriction to an invariant subspace, and of its compression to t…
Characterization of singular numbers of products of operators in matrix algebras and finite von Neumann algebras
Hari Bercovici, Benoit Collins, Ken Dykema +1
We characterize in terms of inequalities the possible generalized singular numbers of a product AB of operators A and B having given generalized singular numbers, in an arbitrary f…
