Italian mathematicians Albano (U. of Rome) and Bove (U. of Bologna) explore the (micro)hypoanalyticity and the Genrey hypoellipticity of sums of squares of vector fields in terms of the Poisson-Treves stratification. Using the Fourier Bros Iagolnitzer (FBI) transform, they demonstrate hypoanalyticity for several classes of sums of squares, and show that though their method is not general, it includes almost every known hypoanalyticity result.
