Abstract
Several related classes of operators on nilpotent Lie groups are considered. These operators involve the following features: (i) oscillatory factors that are exponentials of imaginary polynomials, (ii) convolutions with singular kernels supported on lower-dimensional submanifolds, (iii) validity in the general context not requiring the existence of dilations that are automorphisms.Year: 1986 PMID： 16593640 PMCID： PMC322778 DOI： 10.1073/pnas.83.1.1
