Abstract

We apply the methods of representation theory of nilpotent Lie groups to study the convergence of Fourier series of smooth global solutions to first order invariant partial differential equations D = g in C∞ of a two-step compact nilmani- fold. We show that, under algebraically well-defined conditions on D in the complexified Lie algebra, smooth infinite-dimensional irreducible solutions, when they exist, satisfy estimates strong enough to guarantee uniform convergence of the irreducible (or primary) Fourier series to a smooth global solution. Such strong estimates are not possible on multidimensionaltori. © 1983 American Mathematical Society.
