A note on exponential Riesz bases
Andrei Caragea, Dae Gwan Lee
We prove that if , , are disjoint intervals in with the property that the numbers are l…
On construction of bounded sets not admitting a general type of Riesz spectrum
Dae Gwan Lee
Despite the recent advances in the theory of exponential Riesz bases, it is yet unknown whether there exists a set which does not admit a Riesz spectrum, m…
A note on the invertibility of the Gabor frame operator on certain modulation spaces
Dae Gwan Lee, Friedrich Philipp, Felix Voigtlaender
We consider Gabor frames generated by a general lattice and a window function that belongs to one of the following spaces: the Sobolev space , the weighted…
Quantitative approximation results for complex-valued neural networks
A. Caragea, D. G. Lee, J. Maly +2
Until recently, applications of neural networks in machine learning have almost exclusively relied on real-valued networks. It was recently observed, however, that complex-valued n…
