An energy-concentrated wavelet transform for time-frequency analysis of transient signal
Some signals captured in practical applications are usually composed of a series of modes
that have multivalued time-dependent instantaneous frequency (IF), ie, transient signal …

Jones index theory for Hilbert C∗-bimodules and its equivalence with conjugation theory
T Kajiwara, C Pinzari, Y Watatani - Journal of Functional Analysis, 2004 - Elsevier
We introduce the notion of finite right (or left) numerical index on a C∗-bimodule AXB with a
bi-Hilbertian structure, based on a Pimsner–Popa-type inequality. The right index of X can …
