Wilson bases and ultradistributions
Nenad Teofanov
We give a characterization of Gelfand-Shilov type spaces of test functions and their dual spaces of tempered ultradistributions by the means of Wilson bases of exponential decay. W…
Short-time Fourier transform of the pointwise product of two functions with application to the nonlinear Schrödinger equation
Nuno Costa Dias, João Nuno Prata, Nenad Teofanov
We show that the short-time Fourier transform of the pointwise product of two functions and can be written as a suitable product of the short-time Fourier transforms of …
Continuous frames in tensor product Hilbert spaces, localization operators and density operators
Peter Balazs, Nenad Teofanov
Continuous frames and tensor products are important topics in theoretical physics. This paper combines those concepts. We derive fundamental properties of continuous frames for ten…
Some remarks on analytic pseudodifferential operators
Nenad Teofanov
We report some recent results on analytic pseudodifferential operators, also known as Wick operators. An important tool in our study is the Bargmann transform which provides a coup…
