On a theorem of Chernoff on rank one Riemannian symmetric spaces
Pritam Ganguly, Ramesh Manna, Sundaram Thangavelu
In 1975, P.R. Chernoff used iterates of the Laplacian on to prove an version of the Denjoy-Carleman theorem which provides a sufficient condition for a smooth…
An uncertainty principle for spectral projections on rank one symmetric spaces of noncompact type
Pritam Ganguly, Sundaram Thangavelu
Let be a noncompact semisimple Lie group with finite centre. Let be the associated Riemannian symmetric space and assume that is of rank one. The spectral projecti…
Theorems of Chernoff and Ingham for certain eigenfunction expansions
Pritam Ganguly, Sundaram Thangavelu
We prove an uncertainty principle for certain eigenfunction expansions on and use it to prove analogues of theorems of Chernoff and Ingham for Laplace-…
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.
