On theorems of Chernoff and Ingham on the Heisenberg group
Sayan Bagchi, Pritam Ganguly, Jayanta Sarkar +1
We prove an analogue of Chernoff's theorem for the sublaplacian on the Heisenberg group and use it prove a version of Ingham's theorem for the Fourier transform on the same group.
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…
On Hermite pseudo-multipliers
Sayan Bagchi, Sundaram Thangavelu
In this article we deal with a variation of a theorem of Mauceri concerning the boundedness of operators which are known to be bounded on We obtain sufficient…
Weighted norm inequalities for Weyl multipliers and Fourier multipliers on the Heisenberg group
Sayan Bagchi, Sundaram Thangavelu
In this paper we prove weighted norm inequalities for Weyl multipliers satisfying Mauceri's condition. As applications of this we obtain some estimates for multipliers on the…
