On the Local solvability of a class of degenerate second order operators with complex coefficients
Serena Federico, Alberto Parmeggiani
We study the local solvability of a class of operators with multiple characteristics. The class considered here complements and extends the one studied in [9], in that in this pape…

Global Gevrey hypoellipticity for the twisted Laplacian on forms
Wei-Xi Li, Alberto Parmeggiani, Yan-Lin Wang
We study in this paper the global hypoellipticity property in the Gevrey category for the generalized twisted Laplacian on forms. Different from the 0-form case, where the twisted…
