Poisson transform for the Heisenberg group and eigenfunctions  of the sublaplacian 

 - Bangalore:  Department of Mathematics, Indian Institute of Science:  2006 
 - We define an analogue of Poisson transform on the Heisenberg group and use it to characterise joint eigenfunctions of the sublaplacian L and T = i∂t in terms of certain analytic functionals.
