Near-optimal bounds for signal recovery from blind phaseless periodic short-time Fourier transform
Tamir Bendory, Chi-yu Cheng, Dan Edidin
We study the problem of recovering a signal from samples of its phaseless periodic short-time Fourier transform (STFT): the magnitude of the Fourier transform of…

Variation of Stratifications From Toric GIT
Chi-yu Cheng
When a reductive group acts on an algebraic variety, a linearized ample line bundle induces a stratification on the variety where the strata are ordered by the degrees of instabili…
