Fourier transform and Plancherel Theorem for Nilpotent Lie Group


Kahar El-Hussein
Abstract

As will known the connected and simply connected nilpotent Lie group N has an important role in quantum mechanics. In this paper we show how the Fourier transform on the n  dimensional vector Lie group n R can be generalized to N in order to obtain the Plancherel theorem. In addition we define the Fourier transform for the subgroup NA = A  N of the real semi-simple Lie group SL(n,R) to get also the Plancherel formula for NA
