Weighted estimates for Hardy-Littlewood maximal functions on Harmonic groups
Pritam Ganguly, Tapendu Rana, Jayanta Sarkar
Our aim in this article is to study the weighted boundedness of the centered Hardy-Littlewood maximal operator in Harmonic groups. Following Ombrosi et al. \cite{ORR}, we defi…
Strong unique continuation for variable coefficient parabolic operators with Hardy type potential
Agnid Banerjee, Pritam Ganguly, Abhishek Ghosh
In this paper, we prove the strong unique continuation property at the origin for solutions of the following scaling critical parabolic differential inequality \[ |\operatorname{di…
An analogue of Ingham's theorem on the Heisenberg group
Sayan Bagchi, Pritam Ganguly, Jayanta Sarkar +1
We prove an exact analogue of Ingham's uncertainty principle for the group Fourier transform on the Heisenberg group. This is accomplished by explicitly constructing compactly supp…
Analogues of theorems of Chernoff and Ingham on the Heisenberg group
Pritam Ganguly, Sundaram Thangavelu
We prove an analogue of Chernoff's theorem for the Laplacian on the Heisenberg group As an application, we prove Ingham type theorems for the gr…
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 extension problem, trace Hardy and Hardy's inequalities for Ornstein-Uhlenbeck operator
Pritam Ganguly, Ramesh Manna, Sundaram Thangavelu
In this paper, we study an extension problem for the Ornstein-Uhlenbeck operator and we obtain various characterisations of the solution of the same. We use…
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.
On the lacunary spherical maximal function on the Heisenberg group
Pritam Ganguly, Sundaram Thangavelu
In this paper we investigate the boundedness of the lacunary maximal function $ M_{\Ha}^{lac} $ associated to the spherical means taken over Koranyi spheres on the H…
An algorithm for two-dimensional mesh generation based on the pinwheel tiling
Pritam Ganguly, Stephen A. Vavasis, Katerina D. Papoulia
We propose a new two-dimensional meshing algorithm called PINW able to generate meshes that accurately approximate the distance between any two domain points by paths composed only…
