Spectrum of normal operators that generate certain scalable iterative systems
Pu-Ting Yu
Let be a normal operator on an infinite-dimensional separable Hilbert space and let be a finite subset such that $\{A^nx\}_{n\geq 0,\,x\…
Operations that are incompatible with certain systems of translates in
Pu-Ting Yu
We say that closed subspace of admits a \emph{complete set of semi-regular a-translates} if there exist some , finitely many functions , some subs…
Existence of Unconditional Frames Formed By System of Translates in Modulation Spaces
Pu-Ting Yu
Let and let be an arbitrary subset. We prove that for any with the syst…
Effective nonvanishing for weighted complete intersections of codimension two
Chen Jiang, Puyang Yu
We show Kawamata's effective nonvanishing conjecture (also known as the Ambro--Kawamata nonvanishing conjecture) holds for quasismooth weighted complete intersections of codimensio…
Gabor frames with atoms in M^q(R) but not in M^p(R) for any 1\leq p < q \leq 2
Pu-Ting Yu
This paper consists of two parts. In the first half, we solve the question raised by Heil as to whether the atom of a Gabor frame must be in for some . Spe…
