Completeness of Exponentials and Beurling's Theorem on and

Santanu Debnath, Suparna Sen

A classical result of Arne Beurling states that the Fourier transform of a nonzero complex Borel measure on the real line cannot vanish on a set of positive Lebesgue measure if…

Roe- Strichartz Theorem on Two Step Nilpotent Lie Groups

Sayan Bagchi, Ashisha Kumar, Suparna Sen

Strichartz characterized eigenfunctions of the Laplacian on Euclidean spaces by boundedness conditions which generalized a result of Roe for the one-dimensional case. He also prove…

Uncertainty Principles of Ingham and Paley-Wiener on Semisimple Lie Groups

Mithun Bhowmik, Suparna Sen

Classical results due to Ingham and Paley-Wiener characterize the existence of nonzero functions supported on certain subsets of the real line in terms of the pointwise decay of th…

Segal-Bargmann Transform and Paley-Wiener Theorems on Motion Groups

Suparna Sen

We study the Segal-Bargmann transform on a motion group Rn n K; where K is a compact subgroup of SO(n): A characterization of the Poisson integrals associated to the Laplacian on R…

Segal-Bargmann transform and Paley-Wiener theorems on

E. K. Narayanan, Suparna Sen

We study the Segal-Bargmann transform on The range of this transform is characterized as a weighted Bergman space. In a similar fashion Poisson integrals are studied. Using…
