Uncertainty Principles for the Short-Time Fourier Transform on the Heisenberg Group

Arvish Dabra, Aparajita Dasgupta, Prerna Gulia

We develop a systematic theory of uncertainty principles for the short-time Fourier transform (STFT) on the Heisenberg group. Building on recent developments in modulation spaces a…

Boundedness of Fourier Multipliers and Applications to Nonlinear PDEs for the Strichartz Fourier Transform on the Heisenberg Group

Aparajita Dasgupta, Prerna Gulia

We investigate Fourier multipliers associated with the Strichartz Fourier transform on the Heisenberg group. In particular, we establish Hörmander-type boundedness r…

Weighted Norm Inequalities for the Strichartz Fourier transform on the Heisenberg Group

Aparajita Dasgupta, Prerna Gulia, Sanjoy Pusti +1

In this article, we establish an analogue of Pitt's inequality for the Strichartz Fourier transform on the Heisenberg group . By exploiting the scalar-valued formulat…

Uncertainty Principles for the Strichartz Fourier transform on the Heisenberg Group

Arvish Dabra, Aparajita Dasgupta, Prerna Gulia

In this article, we establish several fundamental uncertainty principles for the Strichartz Fourier transform on the Heisenberg group, including Benedicks' theorem, the Donoho-Star…

Some Versions of Beurling's Theorem on H-type Groups

Aparajita Dasgupta, Prerna Gulia, Sanjoy Pusti +1

We prove an analogue of Beurling's theorem on the H-type groups of certain dimensions after establishing the Gutzmer's formula for the H-type groups. We also obtain some other vers…
